介绍6组共12个1∶4缩尺开缝钢板墙试件往复加载试验研究。试验结果表明,由于钢板中对角拉带作用的存在,开设双层竖缝钢板墙的性能比开设单层竖缝钢板墙的性能更好。根据试验结果并结合理论分析,建议考虑板带端部附加变形影响的开缝钢板墙抗侧刚度与受剪承载力计算公式。以北京长富宫饭店钢框架结构为背景,试设计了一填充开竖缝钢板墙的框架结构,基于结构弹性层间位移角满足要求与墙板屈服时侧移角不小于1/300的原则,介绍了布设开缝钢板墙的方法与结构抗震设计过程,通过对新设计结构与原结构弹塑性时程分析结果及用钢量的比较,表明设置开缝钢板墙不仅可以提高框架结构的抗侧刚度,改善整体结构的抗震性能,而且可以节省钢材,震损后易于更换,是改善框架结构抗震性能的一种有效方法。
This paper introduces the reciprocating loading experiments of 12 specimens of 1: 4 scaled steel plate in 6 groups. The experimental results show that the performance of the double vertical seam steel wall is better than that of the single vertical seam steel wall due to the diagonal tensioning effect in the steel plate. According to the test results and the theoretical analysis, it is suggested that the formula of the lateral stiffness and the shear capacity of the slitted steel plate wall considering the additional deformation of the strip ends should be considered. Based on the steel frame structure of Chang Fu Gong Hotel in Beijing, a frame structure filled with vertical seam steel wall was designed. Based on the principle that the displacement angle between structural elastic layers satisfies the requirements and the lateral displacement angle when wallboard yielding is not less than 1/300 The method and the seismic design process of the seams are introduced. The results of the elasto-plastic time-history analysis of the new design structure and the original structure and the comparison of the amount of steel used show that setting the seamed steel wall can not only improve the resistance of the frame structure Side stiffness, improve the seismic performance of the overall structure, and can save steel, easy to replace after the earthquake damage, is an effective way to improve the seismic performance of the frame structure.
