近期研究表明在高风带和地震易发地带,覆波纹钢板的冷弯薄壁型钢龙骨式剪力墙是一种很有应用前景的新型抗侧力结构体系。最近在北德克萨斯州大学对波纹钢板覆面冷弯薄壁型钢龙骨式剪力墙进行了大量试验研究,试验包括墙体试件在水平单调加载和循环反复加载下的抗剪性能试验。对已有研究成果进行了总结,具体内容包括对墙体抗剪性能的试验研究和有限元模拟,以及对整体房屋体系的抗震性能评估。以表格的形式给出了风荷载和地震荷载作用下波纹钢板覆面冷弯薄壁型钢龙骨式剪力墙的抗剪强度建议值。并通过对6个不同建筑原型进行增量动力时程分析,得到了抗震性能设计的3个主要参数。
Recent studies have shown that cold-formed thin-wall steel keel shear wall with corrugated steel sheet is a new type of anti-side-force structural system with great application prospects in high-wind and earthquake-prone areas. Recently, a large number of experimental studies on corrugated steel sheet-welded cold-formed thin-wall steel keel shear walls at the University of Northern Texas have been carried out. The tests include the shear resistance tests of wall specimens under horizontal monotonic loading and cyclic loading. The existing research results are summarized, including the experimental study of the shear resistance of the wall and finite element simulation, as well as the evaluation of the seismic performance of the whole housing system. The recommended values of the shear strength of the corrugated steel plate keel thin-wall steel keel shear wall subjected to wind load and seismic load are given in tabular form. Through the incremental dynamic time history analysis of 6 different building prototypes, three main parameters of the seismic performance design are obtained.
