Study of welded flange-bolted web connections of steel structures in fire 钢结构栓焊节点火灾行为的试验研究
Steel moment-resisting frames consisting of welded flange-bolted web beam-to-column connections are widely used as lateral load resisting system in regions of high seismic risk, because of their merits of architecture usability ( such as no lateral strut required ) and facilely fabrication. 由梁翼缘与柱焊接、梁腹板与柱高强螺栓连接构成的抗弯钢框架具有建筑和使用的优越性,在强震地区得到广泛应用。
The stress distribution of the welded cut in web structure was analyzed with 3D-FEM, and a series of static compression tests ( three points bending ) were made in the lab. 用三维有限元法分析了腹板焊接型切口结构的应力分布,并进行了静载压缩(三点弯曲)对比试验。
