Performance Evaluation of R.C. Moment Resisting Symmetric Frame using Nonlinear Dynamic Analysis

Engineering structures are often very complex and difficult to analyze for their dynamic, or vibrational, behavior. With the immense loss of life and property witnessed in the last couple of decades alone in India, due to failure of structures caused by earthquakes, attention is now being given to the evaluation of the adequacy of strength in RC framed structures to resist strong ground motions. Modern performance-based design methods require ways to determine the realistic behavior of structures under such conditions. Enabled by advancements in computing technologies and available test data, nonlinear analyses provide the means for calculating structural response beyond the elastic range, including strength and stiffness deterioration associated with inelastic material behavior and large displacements. In general, the study of the inelastic seismic responses of buildings is important to provide economical design by making use of the reserved strength of the building as it experiences inelastic deformations. In the present paper, Performance evaluation of R.C.C. Symmetric frames located in Seismic Zone V is done using Non Linear Dynamic Analysis. It is widely recognized that Nonlinear Dynamic Analysis constitutes the most accurate way for simulating response of structures subjected to strong levels of seismic excitation. This analytical method is based on sound underlying principles and features the capability of reproducing the intrinsic inelastic dynamic behavior of structures. Thirteen Ground Motions are selected in present paper, in which there are seven past Indian ground motions and six artificial ground motions. For this paper 4, 6, 9 storey R.C.C frames is selected for performance evaluation. Due to faster solver system and fiber based concept among all software's SeismoStruct software is chosen to perform Nonlinear Dynamic Analysis. Finally, Performance evaluation is carried out in terms of displacement profile and drift limit from performance criteria mentioned in ATC-40 and Fema-356. Citation: Palak V.
