| 摘 要： | 对钢筋混凝土平面夹心节点(核心区混凝土强度与梁相同)与传统节点(核心区混凝土强度与柱相同)的抗震性能进行了对比分析,内容涉及裂缝开展及试件损伤过程、失效模式、位移延性、核心区抗压承载力、核心区抗剪承载力、滞回耗能性能、梁筋粘结锚固性能、核心区剪切变形等方面。研究显示夹心节点综合抗震性能接近传统节点,但抗剪承载力、梁筋粘结锚固性能等相对较弱。

| Abstract: | Seismic resistant performance of sandwich reinforced concrete beam-column joints is studied while comparing with traditional joints.Integrated results and behaviors,such as stages of cracking and damage,failure mode,ductility,shear capacity,axial compressive capacity,energy dissipation capacity,beam bar anchorage,distortion of the joint region,are investigated.The results of this experimental investigation indicate that the performance of sandwich joints is similar with that of traditional joints.But some a... |
