| 中文摘要 | 共进行了8块组合板试验,研究了缩口型压型钢板-混凝土组合板的破坏特征、纵向抗剪、抗弯等力学性能。试验结果表明,对组合板承载力起控制作用的是纵向剪切破坏和弯曲破坏,对于端部无栓钉的组合板,随剪跨比Ls/dp的增大,破坏形态会逐渐由纵向剪切破坏向弯曲破坏过渡;端部栓钉可以有效改善组合板在极限状态时的受力性能。在试验研究的基础上,分别采用m-k法和部分剪力连接法回归得到了计算该类型压型钢板组合板纵向抗剪承载力的必要参数,同时分析了端部栓钉的有利作用。两种方法均能较准确地预测板的极限承载力。; Eight specimens are tested to study the load-carrying capacities of composite slabs with re-entrant trough profiled steel sheeting.The test results show that longitudinal shear failure and flexural failure are the dominated failure-modes in composite slabs.As L_s/d_p increaseing,the failure modes of slabs without end anchorage changed from the former to the latter.It is also found that end anchorage could remarkably improve the mechanical behavior of composite slabs.Finally,the parameters for m-k method and partial shear connection method are determined for predicting the longitudinal shear strength of the composites slabs based on test results,and the effect of end anchorage is measured.The results provided by these two methods have a good agreement with those obtained from tests.; 高等学校博士点基金资助项目(2000000344) |
