对干式企口梁柱节点缩尺试件模型进行了拟静力加载试验,探讨了其承载力、滞回曲线、骨架曲线、钢筋应变以及延性、耗能等抗震性能。采用ANSYS有限元软件对干式企口梁柱节点试验模型进行了分析计算,并将理论与试验结果进行对比,验证理论研究分析的正确性,探讨了改变预埋钢垫板的位置对结构抗震性能的影响。结果表明:干式刚性企口梁柱节点的滞回曲线形状较为饱满,节点的延性和耗能能力较好;节点具有较高的承载力,满足原结构的设计要求;在实际工程设计中,使用结构内力计算对梁牛腿F部按常规规范法进行配筋设计,梁牛腿R部和缺口梁采用PCI手册计算配筋,节点承载力控制截面即为常规梁端部截面,简化了设计流程。
The quasi-static loading test was carried out on the model test of the beam-column joints of dry bulkhead. The bearing capacity, hysteresis curve, skeleton curve, steel strain, ductility and energy dissipation were discussed. ANSYS finite element software was used to analyze and calculate the experimental model of dry socket-beam beam-column joint. The theoretical and experimental results were compared to verify the correctness of the theoretical analysis. The effects of changing the location of embedded steel plate on the structure anti-vibration The impact of performance. The results show that the shape of hysteretic curve of dry rigid tongue and column joints is relatively full and the ductility and energy dissipation capacity of the joints are good. The nodes have higher bearing capacity and meet the design requirements of the original structure. In practical engineering design, The internal force of the structure was used to calculate the reinforcement design of the F section of the beam and the cow according to the normal standard method. The R and G beams of the beam and the cow were calculated using the PCI manual to calculate the reinforcement. The control section of the bearing capacity of the beam was the conventional beam end section, Process.
