ABSTRACT

Several factors may contribute to improving or reducing the capacity of the structural system against hazardous events, such as earthquake or wind excitation. Among these factors, this present work investigates the effect of soil type, anchorage depth of foundation and the number of stories of a reinforced concrete structure on its stability and integrity. The structures, subjected to seismic forces and the equivalent lateral forces due to earthquake, were evaluated based on EUROCODE 8. The nonlinear static analysis was performed. The response of the examined structure on a fixed base was also presented for comparison. The HAZUS methodology afforded by FEMA was applied to evaluate the fragility curves of various structures with different story numbers. The spectral displacements at the performance point and the probability of damage were evaluated for each level. For comparison, the methodology (HAZUS) was applied to calculate the reinforced concrete building's failure risk without taking the relationship between the soil and the structure into account. This was accomplished using the finite elements program SAP2000. From the results computed, the effect of including the (SSI) in the analysis was clearly observed. The impact of the examined parameters was also clear on varying the seismic behavior of the structure.
