Abstract

Structures designed for typical loading often gets damaged or can collapse during severe earthquakes. The beam column joint is the crucial zone in a reinforced concrete moment resisting frame. This paper presents a behavior of the exterior beam column joint, which is analyzed experimentally and numerically using ANSYS software. Understanding the joint behavior is essential in exercising proper judgments in the design of joints. The objective of the present study is to compare the behavior of exterior bamboo fiber reinforced concrete beam-column joint with different modulus of elasticity, which is detailed as per IS 456 and IS 13920. A three-storied RC building in the zone V is analyzed, and one of the exterior beam-column joints at an intermediate storey is designed in ETABS.15. Two one-third scaled specimens and two detailed as per IS 456 were tested under a reverse cyclic loading. The test results indicate failure accrue in bamboo fiber reinforced SCC beam-column joint and helps to compare the failure pattern with conventional SCC concrete replaced with GGBS and alccofine. Enhancements in the performances of beam-column joints for cyclic loading for different modulus of elasticity (E) values were also observed and nonlinear analysis is carried out in ANSYS software.
