| 中文摘要 | 由于原多层钢框架结构不满足工程要求,需要对原有桁架梁-柱节点进行加固设计。采取的方法是:增焊节点板以及角钢来加强桁架梁端部;桁架梁两侧外焊槽钢来提高梁的整体力学性能。手算节点的焊缝承载力并使用有限元软件校核验证结构加固是否合理。以桁架梁两侧增焊槽钢的位置和数量、梁的端部连接形式为参数,比较6组试件在单调加载和循环加载下的受力特性。结果显示:采用该加固方式是可靠的;增焊的斜槽钢对加固起主要作用,竖直外贴槽钢因位置不同而影响不同。; Due to the original multistory steel frame structure didn't conform to the engineering requirement,it's necessary to strengthen the joint of the truss girder: adding the welding plate and angle steel were added to reinforce the terminal of truss girder. The detail work was calculated the strengthened by hand and computer respectively to make sure that the reinforcement project was safe and reliable. Meanwhile,comparing the properties of six sets of specimens under monotonic loading and cycle loading was done. Conclusion was that the strengthening method was reasonable; the steel channel was added to play a major role in reinforcement project while the vertical steel channel had a different influence at a different location. |
