One flush end-plate external joint under monotonical loading and the other four joints under cyclic loading were tested. Failure modes and the effects of reinforcement ratio and concrete in column flange were synthetically considered during cyclic loading. Results of the experiments show that external flush end-plate composite joint also have quite hysteretic behaviors, better strength resistance and stiffness that are worth to promotion in seismic area.Based on experimental results and plastic analysis simplified formulas on moment resistance of semi-rigid composite joints were introduced.
本文对1个半刚性端板连接组合边节点进行了单调静力加载试验并对4个半刚性端板连接组合边节点进行了循环加载试验研究,主要探讨了节点的破坏模式以及混凝土板内纵向钢筋配筋率和柱翼缘内填充混凝土对节点性能的影响,试验结果表明端板连接组合边节点依然具有良好的滞回性能,较好的延性和耗能能力,是一种值得推广的半刚性梁-柱节点形式。
