复合主轴端板连接的结构特性

设计中，节点最关键的结构性能是其抗弯能力、刚度和转动能力。这些都取决于连接梁的截面高度。对梁截面高度达530mm的复合端板连接进行一系列试验。试验结果显示楼板的断裂通常导致结构失效，但是这一般都发生在该处的转动变形已经充分发展之后。

Stability of Multi-Storey Unbraced Steel Frames Subjected to Variable Loading

Proposed in this paper is an approach of evaluating the elastic buckling loads for multi-storey unbraced steel frames subjected to variable loading or non-proportional loading. In the case of variable loading, the conventional assumption of proportional loading is abandoned, and different load patterns may cause the frame to buckle at different levels of critical loads. In light of the use of the storey-based buckling concept to characterize the lateral sway buckling of unbraced framed structures, the probl...
