| 摘 要： | 利用荷载增量法分析了门式刚架在水平荷载作用下的受力状况,得到刚架在破坏时的极限荷载以及塑性铰出现的先后顺序和出现塑性铰时与之对应的荷载值,通过采取一定措施对节点域进行加强,采取在出现塑性铰的节点域加腋的方式来提高节点的承载力,经计算节点承载力大为提高,使结构具有更大的安全储备,从而使结构具有一定的抵抗超越荷载的抗灾害能力。

| Abstract: | The paper adopts the loading incremental method to analyze the stressed status of the portal frame under the horizontal loading effect,achieves the ultimate loading of the frame when it is damaged and the sequence for the plastic hinge,and its respective loading value,strengthens the joint region with certain measures,proves the loading capacity of the joints by the haunch of the joint region when the plastic hinges appear,and proves the loading capacity of the joint is improved and the structure has large safety reserve,so the structure has certain anti-disaster capacity which can resist the surpassed the loading capacity. |
