矩形钢管混凝土梁承载力的试验和模拟分析
|
摘要
通过对6个宽厚比大于55的钢管混凝土纯弯构件的试验研究和模拟分析,研究钢管混凝土梁的受力性能及影响因素。研究结果表明:钢管混凝土受弯构件具有较高的抗弯承载力和较好的延性,即使跨中挠度达到L/20,作用在试件上的外荷载仍能有所增加。构件的宽厚比对抗弯承载力的影响比高宽比的影响要显著。采用SAP2000模拟钢管混凝土梁受力的全过程,与试验结果吻合较好。
It has been studied and simulated that 6 pure bending of concrete-filled steel tubular members with the ratio of width and thickness being greater than 55. It has also been studied that the forced behavior and influencing factors of the steel tube concrete beams. The study results show that the concrete-filled steel tube bending members have high flexural capacity and good ductility. Even the cross-section deflection reached L /20,the load of the specimen on the outside can still increase. The effect of ratio of width and thickness is more significantly than that of the ratio of height and width on the flexural capacity of the member. It has been adopted SAP 2000 to simulate the forced full process of the steel tube concrete beams,whose result agreed well with the test result.
