Case Study for Evaluation of Dynamic Characteristics of Adjacent Buildings

In this paper, the influence of soil type and distance between adjacent buildings on structural dynamic properties (natural frequencies and damping ratios) is investigated. For this purpose equations of motion for two adjacent buildings, which affect each other’s dynamic responses, are developed. For modeling soil and its effects, springs and dampers in the base level is used. Finally, by studying a real building, its dynamic properties in case of being located adjacent to another same building and individually are calculated and compared. In previous researches, these dynamic properties were calculated by experimental methods. By comparing analytical and experimental results, it is found this proposed model calculate the values of dynamic properties with good precision.
