Importance of Web Reinforcement in Beam Column Joint Connections

Abstract

The primary focus of this research is to determine the optimal stirrup configuration to prevent shear failure. This project aims to investigate the behavior of beam-column joint frames under concentrated loads. Specimens with dimensions of 700mm x 500mm and cross-sectional dimensions of 200mm x 100mm, using M30 Grade concrete, were prepared for this study. The specimen was tested in the linear, non-linear range and up to ultimate load limit for a concentrated load. The load responses are measured with LVDT & Data logger in this experimental work. The code of practice recommends (Bureau of Indian standards-13920-1993) the bond, shear, and ductility, reinforcement for shear and moment carrying capacity. This code aims to fulfill both bond and shear requirements. This paper provides a thorough review and offers recommendations on the design and detailing of beam-column joint connections. Analytical value of the load carrying capacity of the beam column joint was assessed using limit state method by eliminating the partial safety factors for the load and strength. The results were compared between experiments and analytical values and suggestions are presented in this paper.
