Study the seismic response of reinforced concrete high-rise building with dual framed-shear wall system considering the effect of soil structure interaction

Abstract

Abstract During strong earthquakes, civil structures are subjected to damaging forces. Tall buildings if damaged would threaten the life safety of inhabitants or at least would cease to offer the same level of functions. For this reason, tall buildings should be designed in accordance with the seismic provisions that ensure suitable performance during and aftermath. One of the factors that dominate tall buildings’ design is the dynamic soil-structure interaction (SSI) that differs significantly with the variation of several aspects. Soil type that incorporate the building’s foundations, the height of the building, the type of lateral load resisting system, and many other factors. In this research authors have considered SSI using the direct method (i.e. FEM soil medium) and studied the effect of changing soil type (soft soils and hard soils) on the performance of the tall building under consideration. The building was taken to be 16 stories, wall-framed dual system for seismic loading resistance. Semi-infinite elements from Abaqus (simulia’sAbaqus 6.14) solid element library were used to model the boundaries of soil media. The seismic loading input was El-Centro acceleration time-history record. Results of analysis showed differences between soft soil and hard soil types, especially on the displacements and base shear values.
