Seismic Behaviors of RC Buildings in Slopping Ground

This thesis is the study of seismic behavior of RC building in hilly areas i.e. sloping grounds. The study of dynamic response of structure on hilly areas has been done. Almost 13 configuration of structure has been considered for analysis. Six of them are step-back and which consider ground slope. Six are set-back configuration which is like in plain land. Remaining one is plan buildings. Three models are normal step back, setback and plan buildings and remaining are combination of shear wall, steel bracings. Various literature reviews of studies on the seismic behavior of RC building on hilly areas i.e. sloping ground has been studied and presented in this thesis. All considered configuration of building is modeled using ETABS v20.0.0 and IS 1893:2016 and analyzed by using equivalent static analysis and response spectrum methods. Then considered buildings have been compared in terms of base shear, Fundamental time period, top storey displacement, drift and story stiffness. The seismic behavior of building on hilly areas (sloping ground) is found differ from building plain ground. Most of studies lead to conclusion that building on hilly areas (sloping ground) has higher displacement and base shear compared to building on plain land. Also conclude shorter column attracts more forces and cause damage when earthquake occurs. Step back configuration could prove more vulnerable to seismic activities. We also concluded that building with shear wall improves seismic behavior of building by increasing strength and stiffness and also reduce in deflection.
