SEISMIC DESIGN OF MULTISTORY BUILDING WITH DIFFERENT SOIL CONDITION

Abstract

The current version of the IS: 1893-2002 requires that practically all multi storied buildings be analyzed as three-dimensional systems. Buildings may be considered as symmetric in plan, in mass and stiffness along storey, of the buildings. By using the latest software STAAD Pro, the study will analyze and compare the seismic response of a G+15 storey RCC frame structure with variable soil conditions (Hard, Medium and Soft soil) for seismic Zone IV.

The structural & seismic parameters are kept same for Model M1, M2 & M3 except the soil type. All models are analyzed in STAAD Pro V8i software using the Equivalent Static method of seismic analysis. The response of the model is examined in terms of the maximum storey displacement, base shear and story drift. The objective of the study is checking the stability of the three models in different soil type conditions.

The objective of the project is to carry out Response spectrum analysis (RSA) of regular RC building frames with different types of soil. Comparison of the results of analysis with and without seismic effect regular structure will be done.
