| 摘 要： | 为了解决圆钢管轻集料混凝土梁与混凝土桥墩的整体连接问题,共设计了穿心钢筋、穿心钢筋加弯矩传递板和穿心工字钢3种节点连接形式,采用拟静力试验研究了刚节点在低周反复荷载作用下的抗震耗能性能。试验结果表明,3种节点都具有良好的抗震耗能性能,等效粘滞阻尼系数都超过了钢筋混凝土结构要求的0.1,延性系数都大于规范规定的2;在节点屈服以后,3种节点仍然具有一定的承载力,其中穿心钢筋和穿心工字钢节点的延性系数和等效粘滞阻尼系数基本相同,穿心钢筋加弯矩传递板较其他2种刚节点稍差。

| Abstract: | In order to study the performance of the connections between lightweight aggregate concrete filled circular steel tube beam and reinforced concrete pier,three types of connections are designed in this paper,including piercing reinforcing bar,piercing reinforcing bar with moment transfer plate and piercing I-beam. The energy consumption of these three kinds of connections under low frequency cyclic loading is studied by pseudo-static testing.The results indicate that all the connections have good energy cons... |
