Investigating the factors affecting the vulnerability of worn-out structures in urban areas using SPSS (Case study: Fereydunkenar city)

The worn-out urban structure is the whole or that part of the urban space whose biological system has been disrupted and dysfunctional both in terms of construction and the function of vital components. In this study, an attempt was made to get acquainted with the worn-out structure and the degree of vulnerability in dealing with unexpected events, and after identifying the factors, to investigate it to reduce the amount of damage. For this purpose, field studies were performed and the use of past experiences as well as preparing and distributing responses among those involved in disaster management measures to assess the current strategies of the crisis management cycle to analyze them to adopt appropriate strategies.

The present study is an applied and descriptive-statistical work. The statistical population composed of 60 people and experts involved in crisis management and services and organs and services in disasters and accidents such as crisis management, fire and safety services.

Each of the factors affecting the vulnerability of worn-out structures, such as the network of passages, housing, green space, medical and relief centers, bridges and underpasses, water, gas and telecommunication electricity networks, have a normal distribution, because (0.05 = α <sig).

Studies have shown that at the 99% confidence level (α = 0.01), each of the above factors are effective, and in the analysis, the order of effectiveness showed that at the confidence level, 99% (= 0.01) α). The order of influence of each of the factors affecting the vulnerability of worn-out tissue is different, because (α = 0.01 = Sig = 0.0001). Therefore, in ranking the factors affecting housing vulnerability (Bamyangin Rating: 4.57) the highest and green space (Bamyangin Rating: 2.32) have the lowest priority.
