Increasing opportunities for social interaction is one of the necessary psychological needs, which causes problems in human's personal and social life. The increase of residential complexes and apartment living in the current century, which occurred following the increase in population in Iran, has become an inevitable issue. Neglecting psychological needs in the design of today's residential complexes and only providing physical needs leads to social anomalies. In this research, an attempt is made to investigate the increase of residents' interactions in the open space of the complexes, considering the constructive components of social relations. The current research is a survey descriptive research and in terms of its purpose, it is applied research. Research method, survey method and data collection tool, the researcher made a questionnaire. After categorizing and selecting the target population, a questionnaire was prepared. Then the data were collected to check the relationship between the variables to test the research hypotheses. The collected data have been analyzed using SPSS version 25 software.

The rise of modernism in architecture and urban planning, along with the growing population of the city, restrictions on land and services, demand for housing and economic and environmental constraints, high-rise construction in major cities and the location of these buildings in urban spaces became very important. And it became a good way to control the physical growth of cities and it was necessary to identify suitable areas for the construction of high-rises. The main purpose of this study is to identify suitable areas for the construction of high-rise buildings in Gorgan. This research is of applied type and in terms of nature and method is descriptive-analytical. Data collection was done by documentary and survey methods with a statistical population of 10 people as a sample of municipal urban planning specialists and managers. After examining the influential factors, criteria were determined in four dimensions including physical, social and cultural, environmental and economic. Weighting was performed according to the AHP model and the layers were superimposed using the GIS system. Findings show that areas in the east, west, southwest and center of Gorgan, have a good capacity for the construction of high-rise buildings; In such a way that high-rise construction in these zones leads to proportional distribution and appropriate building density and population in the city , and in the end after prioritizing the zones; Based on the findings, suggestions were made for the establishment of high-rises in suitable areas.

With the arrival of Islam, Iranian architecture, which had significant technical values before the advent of Islam, with the advent of Islam, emerged the doctrinal and fundamental beliefs that placed Iranian-Islamic architecture among the modeling architectures. Patterns that evolved in the historical course of this architecture and became significant and sometimes unique features of Iranian-Islamic architecture. Iranian-Islamic modeling architecture has been neglected in recent decades in dealing with Western architecture, and values derived from its IranianIslamic identity and culture has been ignored.

The present research paradigm is free research and a combination of analytical methods, the use of questionnaires, Delphi and correlation tests. Iranian-Islamic architecture is placed and the results obtained by SPSS software are analyzed to evaluate the correlation of indicators.

The findings of Pearson correlation analysis show a significant direct and upward relationship between patterned architecture with the criteria of symbolic vision, conceptual architecture, spatial hierarchy, environmental adaptation, cultural adaptation, readability, semiotics, general acceptability and Iranian-Islamic architecture.

The results of the research show that in order to return to the Iranian-Islamic models in the design of today's high-rise residential buildings, two groups of indicators that are discussed in the form of ethics (mental indicators) and human-centered (physical indicators) are more than others. Factors and indicators are influential and desirable based on Iranian-Islamic architectural patterns.

This research investigates the role of aesthetics in improving the quality of urban landscape with the aim of evaluating the 45-meter-wide El-Goli boulevard with emphasis on the high-rise items through the parameters and indices extracted from the research based on theories of scholars of experts and authors. The research method is mainly descriptive, analytical, and field. The required information of the present research collected through the various sources as comparative-analytical using library resources, documents, records and reports and the remaining part collected by visiting governmental organizations including municipality-district 2, Organization of green space and parks. Based on field studies, data including Panoramic photography and objective observations from both two sides of the El-Goli Blvd. in four sequences collected. The statistical society compromises 500 people in four groups consisting of experts and administrators of this field, professors and students of architecture of Tabriz University and citizens (including tradespeople, residents and passers-by), domestic and foreign tourists. The logic of sampling for selection the study area and statistical society are targeted and randomly respectively. Data analysis is carried by SPSS software. One-way variance test was used among the four groups of studies to compare the dimensions of the visual quality for the urban landscape of high-rise buildings in 45 meter El-Goli boulevard. The results of the study indicate non-satisfaction of the citizens, experts, managers and experts regarding the urban visual quality of high-rise buildings on 45-meter-wide El-Goli Blvd. which requires improvement and co-ordination among all the groups participated in this study.

As a product of population growth and increased urbanization as well as insufficient land for construction, high-rise construction and vertical spatial development have increased unprecedentedly during the recent decades. This type of construction, considering its characteristics, despite its positive effects, faces restrictions and threats which result in several difficulties including heavy traffic, remote workplace, environmental pollution, excessive urban development on farmlands, and wasting time. In most cases, physical development is surpluses to population growth. Today, locating high-rise buildings is a necessity which is assigned much importance in urbanism due to environmental issues and climatic conditions of an area. The case studied in this paper is the city of Qazvin. The purpose of this paper is to analyze the effective factors in location of high-rise buildings with emphasis on environmental sustainability in the city of Qazvin. The research method is descriptive- analytical and based on application and development. Results from TOPSIS model used in this study show that there is no pattern for location of high-rise buildings in Iran and disorganized criteria provided regardless of urbanism or effective factors lead to environmental degradation. Results also show that economic, environmental and physical factors and land use (0.695, 0.457 and 0.405) are in first to third place indicating their relatively high importance compared with other factors. Construction of high buildings has always provoked controversy among architecture and urbanism scholars. High- rise buildings were constructed in order for optimum utilization of land in metropolitan centers but gradually, as cities expanded, more necessity for buildings in other urban areas arose.
Considering its approach, this study is applied- developmental with a descriptive- analytical method. The data was collected using library method and various statistical sources including nine main components; economic, managerial, socio-cultural, aesthetical, environmental, etc. According to the method, problems are handled systematically and their different components are analyzed. Effective variables, acquired through descriptive and library methods, are identified, indicators appropriate for component analysis are set and variables are studied using TOPSIS.
Results from TOPSIS indicate that from nine studied components, economy is in the first place. Large size and less density ofIranian cities resulted in the use of suburban agricultural lands, porous urban land and harmful economic and environmental effects which impose heavy loads on government and citizens. Therefore, optimal use of availableresources in the cities is necessary (Azizi, 2004: 137). Accordingly,the relationship between density, land price and housing is the main economic aspect of urban density standards. Due to the important role land price and housing play in house price, fluctuations in land price has a great effect on the area of land and house infrastructure and as a result building density. According to experts and elites, second component is the environment, so that, during recent decades, environmental sustainability has been considered as a sustainability aspect in high- rise construction which, according to some researchers, has been neglected as a result of land conditions and environmental problems occurred especially in third world countries. Land use and fabricare in the third place. Traffic is fourth component indicating its effect on locating high-rise buildings, since proper access is an important indicator of urban space utility in this variable.
Due to favorable weather condition and view, quiet space and adjacency to business areas, high- rise buildings of most cities including Qazvin are demanded a lot. Provided that there is no traffic and with normal speed of cars, the distance and time to pass major access routes for the city of Qazvin is reasonable.
Management is fifth component which can play major role in locating high-rise buildings, since proper planning and map for construction of these buildings depends on management which is very important to construct this type of buildings.
Society- population component is in sixth place according to which the density in high residential buildings in social aspects is discussed. High population density in space and high- rise buildings have negative effects including reduced human activities and resultant increased boredom and increased isolation which indicate reduced satisfaction levels from high-rise buildings forms and sizes .
Cityscape is seventh component in which the function, identity and beauty of buildings are very important. In terms of function, Lynch believes that an open landscape of public buildings, whichlead to more relationship between people, can be welcomed by public, otherwise they will be ignored. Hence, the function of such buildings in cityscape is important.
By aesthetical aspect, physical aspect of buildings in cityscape and by physical aspect of high-rise buildings, their form and effect on cityscape are intended.
Climate is in ninth place and the type of climate is discussed in it since position and direction of buildings are very important.
High-rise construction has been used for over half a century in metropolises. Building high residential buildings and towers in high and semi-high and also attached and detached forms in various cities prove the claim. Qazvin was no exception and towers have been built in various parts of the city with different purposes. Rapid and uncontrolled growth of population followed by excessive demand for house as well as preventing horizontal development of cities made high-rise building a solution to land problems. Results show that there are effective factors in locating high-rise buildings including; socio-cultural, fabric and land use, transport, climate, economy, cityscape, population and environment. Findings show that economy (0.695) was the first and most important component considering its corresponding costs. Environment (0.457) was second. A sustainability aspect in high-rise construction is considered in this component which has been ignored, according to some researchers, due to land conditions and environmental problems caused by human activities especially in metropolitan areas and more attention is required when implementing urbanism plans, since some scholars believe in environmental sustainability as the main goal of sustainable development. Fabric and land use was in third place (0.405). Therefore, these three components had the highest impact and importance compared to other components that represents their priority in locating high-rise buildings to minimize scale-based economy, land saving and other problems

Given the increasing growth of urban population, limitation of land and services, also, increasing demand for housing, economic and environmental limitations; high-rise building is a proper solution to control the physical growth of cities. Therefore, identification of suitable zones for construction of high-rise buildings is essential, and of great importance for the proper growth of the city. The aim of this study is to determine the appropriate zones with high potential for the construction of high-rise buildings in the city of Ardabil. In this study, the MCDM methods, including VIKOR and ANP, also 19 subcriteria of 4 main criteria, were used to determine the suitable zones. We benefited EXCEL, GIS, and SELVA IDRISI softwares for data analyzing. Research findings suggest that the east, west and north-east zones of the city, have more potential for high-rise building construction. So that high-rise construction in these zones can lead to proper distribution of construction and population in the city. In conclusion, appropriate zones for the establishment of the high-rise buildings in Ardabiil city, are suggested.

Wind on land is an important factor for the exchange of heat and transportation of microscopy and non-microscopic particles from one point to another. So it has important role in reducing pollutants entering the urban spaces. The physical elements of the urban tissue, such as orientation of the streets and distribution of high-rise buildings have important role in secondary patterning the wind flow. Because of Tehran Elahiyeh is one from the densest of urban tissues in north of Tehran city, so wind features was evaluated in this part because of showing this tissue role in weather pollutants increasing. For this purpose, hourly data of wind velocity and orientation of North Tehran meteorological station (Aghdasiyeh) in period 1988-2009 was used. Wind speed changes in the Elahiyeh area tissue were evaluated in heights of 2 and 10 meter because of different features of station around tissue. The wind speed of threshold was calculated to remove the heat island effect, then the predominant wind directions and theirs frequency was evaluated. Accordingly, the district tissue was simulated using the Arc Scene of ArcGIS software. Also, the effects of high-rise buildings on wind flow patterns were studied for samples buildings by the Reynolds Law. Results are indicator important decrease of wind velocity in Elahiyeh area tissue in compared to station tissue due to high-rise buildings in this tissue. Annual and seasonal frequency of wind velocity indicated that more of % 60 from winds frequency is calm and dominate wind directions are west north-east south and north-south. Simulation of area tissue showed that the highest tissues are exactly in direct of dominate wind. Theses tissues prevent from flow of wind that consequently increase pollution and Thermal Island at area. Amount of threshold wind in three of statistical periods indicated that threshold wind velocity is low so it prevents from weather suitable ventilation in area. Calculation of Reynolds number for samples buildings in area showed that Reynolds number is more of 200000 that is indicator random whirlwind in cannon trail area.

Today, issues such as: the rapid increase in urban population, increasing migration to urban areas, the need for housing in urban areas, land shortages, high prices and a horizontal expansion of cities has led to strongly consider the construction of tall buildings. In this study,the problems of high-rise buildings in the southern regions of Zayandeh river in Isfahan has been examined and a number of high-rise buildings in regions 5, 6 and 13 has been analyzed. The importance of this research is that tall building in the southern regions of Zayandeh river many different effects on the city and its residents are and In recent years, high-level non-procedural soft-peddling in the city, especially in these areas has been made.
This research was functional and cross – sectional study. Combination of data collection methods and survey library. In this study, SPSS software for statistical analysis and GIS software for mapping was used.
The results of the study indicate that: In recent years without procedural tall building in the city and particularly in the southern regions of Zayandeh river taken. High-rise buildings in the southern regions of Zayandeh river has had negative effects on Including obstruction of vision and perspective of the surrounding buildings, to prevent wind flow in the city, traffic impact, social – cultural issues and … . Tall buildings and their status in the regions 5, 6 and 13 cause the difference is the amount of traffic. so that traffic in the area 5 is higher than the 6 and 13. Social and cultural issues created by tall buildings in zones 5, 6 and 13 were different. District 13 has been the most social and cultural issues.
