Study on the Behaviour of RC Bare Frame for Lateral Load

Abstract

This paper presents an experimental investigation on the behaviour of a 2D single bay two storey reinforced concrete (RC) bare frame. RC bare frame is casted in the laboratory to a scale down of 1:3.25; the dimension of frame is 2.3 m height and 1m width. The cross section of beam and column are 100mm x 70 mm. The proposed model is subjected to lateral load at each storey level and their performance was assessed based on load carrying capacity and deflection. The present study includes the entire range of loading from the initial elastic stage until the ultimate failure stage. Analytical study was also conducted for the similar RC bare frame; analytical results were obtained using finite element analysis software Etabs-13. Analytical results were compared with experimental results and it was found to compare well. Keywords: 2D RC bare frame, pushover analysis, lateral loading frame, behaviour of bare frame.
