The building structures situated in hilly areas are much more prone to seismic environment in comparison to the buildings that are located in flat regions due to irregularities in plan as well as elevation. Structures on slope differ from other buildings since they are susceptible to severe damage when subjected to earthquake excitation. The columns have varying height due to sloping terrain. Structures may be analyzed under earthquake loadings, with or without considering the effect of soil structure interaction (SSI). In this present study, an attempt has been made to study the effect of slope angle (viz. 30°, 45°) variation for the structures resting on two-way sloping terrain, considering fixed base structures. The configuration as step back-set back building structures with plan regularity & irregularity has been adopted. This study has also evaluated the behavior or the overall performance of those structures in terms of dynamic characteristics like Fundamental time period, Base shear, Storey drift. The analysis is performed in Linear static method or Equivalent Static Frame Method (ESFM), Linear dynamic method or Response Spectrum Method (RSM), Nonlinear Static Method (NLSM) or Pushover Analysis and Nonlinear Time History Method (NLTHM). Results expose the vulnerability and also show more efficient structure between the aforesaid building structures associated with increment of slope angle in two-way sloping ground.
