冷弯薄壁型钢灌浆墙体抗震性能研究进展

Research advance on seismic performance of cold-formed thin-walled steel grouting wall

与传统冷弯薄壁型钢墙体相比,冷弯薄壁型钢灌浆墙体具有优越的整体刚度和抗震性能。通过综述国内外具代表性试验与有限元分析结果,分别分析墙架柱、支撑、墙面板、抗拔件、砂浆、高宽比、加载方式、开洞情况、竖向荷载作用等影响因素对墙体抗震性能的规律,提出该类墙体在抗震性能方面的研究方向。

Compared with the traditional cold-formed thin-walled steel walls,the cold-formed thin-walled steel grouting walls have superior overall stiffness and seismic performance.By summarizing the representative tests and finite element analysis results at home and abroad,the effects of such factors as wall frame columns,bracings,wall panels,pull-out parts,mortar,height width ratios,loading modes,openings and vertical loads on the seismic performance of the wall were given respectively.The research direction on the seismic performance of this kind of wall was put forward.
