Seismic Response of Cellwise Braced Reinforced Concrete Frames

Abstract

This paper present an elastic seismic response of reinforced concrete frames with reinforced concrete braces in K or inverted – A or V – braced pattern which are analyzed numerically for twelve storey building with 5-bay structures. The responses of braced frames of different patterns (bay, level and combinations thereof and particular cell braced) have been compared with each other and the same also have been compared with unbraced i.e. bare frame. With this view point all parameters in dimensionless form, to include geometry of frame, axial forces, shear forces, bending moments, displacements, location of bracing etc. have been used. Results and finding can be directly used to predict the behavior of real life structures which are concluded from graphs and comprehensive discussions.
