DYNAMIC ANALYSIS OF RCC BUILDING FRAME WITH MASS AND STIFFNESS IRREGULARITIES FOR VARIOUS PLAN GEOMETRY

  • Unique Paper ID: 188469
  • PageNo: 1925-1931
  • Abstract:
  • It is very essential to identify the behavior and damages of buildings, which initiate at locations of the structural weak planes present in the building systems, due to various shape of building i.e., Rectangular, L-Shape and T- Shape building. The contribution of lateral load resisting system, number of stories, type and different type of analysis method has to be properly assessed and evaluated in order to avoid torsional effect and collapse of the structure. The behaviors of building during earthquake depends critically on its overall shape, size and geometry. Buildings with irregular geometry respond differently against seismic action. Plan geometry is the parameter which decides its performance against different loading conditions. The effects of irregularity (plan and shape) on structure have been carried out by using structural analysis software ETABS 2018. The aim of present study is to compare seismic performance of Equivalent Static Method, Response Spectrum Method using medium soil. The G+15, G+20 and G+25 story structures situated in earthquake zones III. All frames are designed under same gravity loading. Response spectrum method is used for seismic analysis. ETABS software is used and the results are compared. The results were obtained in the form of Earthquake Displacement, Story Force, Base Shear and Modal Mass Participations.
