Study on Comparative Study of Seismic Analysis of RCC Building Frames

Abstract

It's a common misconception that masonry infill in structural steel or reinforced concrete frames can only increase overall lateral load capacity and, as a result, is always beneficial to seismic performance. If the masonry infill is ignored throughout the design process, it is plausible to assume that each frame in each direction is subjected to about equal seismic lateral loads due to structural symmetry. Infill has the true effect of stiffening frames in compared to other frames. As a result, the natural period of the structure will shrink, and seismic forces will grow in lockstep. . Furthermore, due of their higher stiffness compared to the other frames, the fraction of total seismic shear transmitted by infilled frames will rise. Shear stresses in the panels are principally responsible for transmitting the high shear forces generated in the infilled frames.

The goal of this study is to compare and analyse a multi-story 3D-RC frame construction with and without infill for a seven-story building utilising STAAD-PRO. The modal analysis of a structure is used to determine whether the structure's stiffness and mass are accurate.
