A REVIEW ON PERFORMANCE EVALUATION OF RC MOMENT RESISTING ASYMMETRIC FRAME DESIGNED USING INCREMENTAL DYNAMIC ANALYSIS

Abstract

as the world move to the accomplishment of Performance Based Engineering philosophies
in seismic design of Civil Engineering structures, new seismic design provisions require Structural
Engineers to perform both static and dynamic analysis for the design of structures. There are so many
methods are evolved to evaluate the seismic capacity and demand of the structure for different seismic
excitation. One of the common method used for evaluation of the capacity of the structure is incremental
dynamic analysis. Now a day, Incremental Dynamic Analysis (IDA) is emerging as an accurate tool to
estimate the capacity of the structure. It involves subjecting a structural model to a number of groundmotion records, each scaled to low severity to high severity.
This parametric study involves safety consideration of RC frames with variation in demand. The
behaviour and performance level of the structure in different seismicity have been studied. The results
have been compared on basis of base shear versus roof displacement graph, inter-storey drift ratio and the
hinge formation mechanism. The study will illustrate the behaviour of the structure for seismic actions and
the performance and damages to structure will be acquired. The results will show the proper response of the
structure under different seismic loads.
