SEISMIC PERFORMANCE OF RC FRAMED BUILDINGS UNDER LINEAR DYNAMIC ANALYSIS

The construction of multi-storey buildings is increasing constantly all over the world. The development of highly advanced structural system is mainly based on the quality of aesthetic expression, structural efficiency, and geometric versatility. The selected structural system should be such that it has to be effectively utilized for structural requirements. The unique geometrical configuration of the diagrid structural systems have driven them to be used for high rise buildings providing the structural efficiency and aesthetic potential. In this present work, four different models of I section of a 30 storey RC Frame building with plan size 18 m × 18 m located in seismic zone V have been considered for analysis. Steel diagrid structure of 2 storey and 6 storey models and Infill wall model are analyzed and compared with conventional RC Frame model and is studied using linear dynamic analysis. ETabs software is used for modeling and analysis of structural members. Comparison of analysis results in terms of storey Displacement, Drift, Bending Moment, Axial forces, Time period, Base shear is presented and the results obtained were compared with those obtained from other models.
