Ambraseys ISSN: 1363-2469 print / 1559-808X online DOI: 10.1080/13632460802211941 Seismic Behavior of Reinforced Concrete Interior Wide-Beam Column Joints SUDHAKAR APPARAO KULKARNI and BING LI School of Civil and Environmental Engineering, Nanyang Technological University, Singapore 9 0 0 In this article, experimental and finite element (FE) numerical investigations on interior wide-beam 2 y column joints are presented. The experimental research consisting of three full-scale interior wide- a M beam column specimens was carried out at Nanyang Technological University, Singapore to study 5 2 the seismic behavior. Details of the test results are discussed to understand the specimens’ seismic 7 2 performance in terms of general behavior, hysteresis loops response, and strain profiles of long- : 5 0 itudinal reinforcement. In the FE numerical study, the three-dimensional (3D) model developed is : validated by comparing the analysis results with the experimental test results, which has shown a t A ] good agreement. A parametric study is performed to elucidate more information and to understand y t the influence of critical parameters affecting the joint behavior such as column axial load, beam i s r anchorage ratio, and wide beam participation. e v i n U
