Earthquakes are natural phenomenon, which can occur anytime, anywhere. They can cause significant damage to a structure and irregular buildings suffer more damage compared to regular buildings. Irregular buildings constitute a major portion of the modern urban infrastructure and hence it is necessary to understand the behavior of such buildings under seismic loads, which could help prevent damage due to the effects of an earthquake. The objective of this study is to carry out nonlinear static analysis of regular and irregular Reinforced Concrete (RC) frame buildings. The analysis is carried out on a G+8 RC frame building. The shapes considered for comparison are: square, plus, T and inverted L. Analysis is done using equivalent static method, and response spectrum method; further, pushover analysis is carried out. Different types of frames are modeled using ETABS software. The results are compared in terms of displacement, axial force, bending moment, time period, base shear, performance point (base force, displacement) and ductility ratio. The formation of hinges is also observed for all the models.
Earthquakes are natural phenomenon that are unpredictable and cause sizable
destruction in structures. Stiffness, ductility, lateral strength and simple and regular
configurations are several factors which the behavior of a building during or after
the occurrence of earthquake. Hence, it is important to understand the concept of
seismic analysis and apply it while designing any structure. It might help a structure
to withstand seismic loads which could cause failure in many different ways. To
reduce all these damages and to make a structure more durable and efficient during
or after the occurrence of an earthquake, seismic analysis has to be understood and
also carried out. A proper understanding of seismic effects on structures can help in
Soil-Structure Interaction (SSI) is the process in which the response of soil
influences the motion of structure and vice versa. The effect of this interaction becomes
