装配式混凝土梁柱节点试验及受力性能分析
Experiments and mechanical behavior analysis on precast concrete beam-column joints
摘要
Abstract
Four types of beam‐column joints were tested under cyclic loading to investigate the seismic behavior of the precast concrete beam‐column joints .One was cast‐in‐situ monolithic joint and the other three were connected by I section steel ,steel sleeve and improved I section steel ,respectively . The simulated results of the cast‐in‐situ joint under cyclic loadings were accurate when shear stress‐strain relation of the joint core was considered . For three types of precast concrete beam‐column joints ,a simplified method was presented to simulate the skeleton curve of lateral force and displace‐ment based on the equivalent concrete modulus and reinforcing steel yielding strength identified by the test results .The experimental results show that the beam‐column joints connected by improved I sec‐tion steel has the optimalizing peak load and the plumpest hysteresis loop .关键词
