中文摘要	为研究半刚性连接组合梁钢框架在水平荷载作用下的特性,进行水平荷载作用下足尺的空间两层两跨半刚性连接组合梁框架的试验研究。半刚性连接组合梁框架由热轧H型钢柱和焊接H钢梁及压型钢板混凝土组合梁组成,连接为平端板连接半刚性节点。试验主要进行相应测点的应变、转角及位移测量,框架整体性能及半刚性连接节点性能的分析。试验结果显示半刚性连接组合梁框架具有较强的抵抗水平荷载的能力;平端板连接组合节点为半刚性连接、部分强度节点,具有较高的强度、刚度和较好的延性。将试验结果与简化计算方法的预测结果进行比较,结果显示框架的总体位移、极限承载能力、节点转动能力及强度的试验值与简化方法的预测值能较好的吻合。; An experimental study was conducted on the behavior of steel frameworks with semi-rigid composite flush endplate connections under lateral loading.One full-scale two-story two-bay semi-rigid frame model composed of hot- rolled steel column and welded steel beam combined with concrete slab was tested to failure.The strains, displacements and rotations at some key locations of the steel columns and the composite beams were measured.The test results indicate that the strength,stiffness and ductility of the composite flush endplate connections,acting semi-rigidly,are reasonable.The model frame was also analyzed by using a simplified method and the analytical results were compared with those from the tests.It was found that the overall displacement response and load-bearing capacity of the frame and behavior of the connections predicted by the simplified method were in good agreement with the results from the tests.; 国家杰出青年科学基金(50225825)
