Seismic Fragility of Buildings Subjected to Pounding Effects with Soil–Structure Interaction

In this paper, seismic analysis is performed for multi-storey buildings with soil structure–interaction considering pounding effect. Parameters including displacement, shear force, bending moment, and drift ratios are compared for various models. The nonlinear dynamic analysis, i.e. most accurate with time history, is performed on these building structures to compare their behaviour during different strong EQ ground motions. M20-grade concrete and Fe500 steel are used as material of RCC. The structure was assessed again and again for such properties of SSI and pounding. Further corrections are made to these frames so that it meets the minimum requirement possible to make it stiff and sufficient strong to sustain in strong EQ motion. It is observed that the building frames with different storey height exhibits 8% and 23% higher defection than building frames with same storey height at top and bottom levels, respectively. Reduction in moment is observed to be 41.63% for building frames spaced faraway that of closely spaced frames. Hence, the results shown here are for the worst situation possible under the action of SSI effect and pounding.
