【摘要】 对砌块砌体结构进行Push-over分析,其结果准确与否和结构的极限性态目标位移的可靠确定关系很大。本文基于大量的配筋砌块砌体墙片试验结果,对直接基于位移的抗震设计法进行改进,使之能够用于砌块砌体结构的极限性态目标位移的确定。用改进的方法求解一座1/4比例的10层砌块砌体模型结构的极限性态目标位移,并与该模型结构的振动台试验结果进行比较。结果说明本文提出的改进方法是可以应用于求解砌块砌体结构的极限性态目标位移的。更多还原

【Abstract】 The accuracy of pushover analysis for block masonry structures lies strongly on the target displacement of the structure. Based on the testing results of a large number of reinforced block masonry walls, this paper developed a method that can be used to determine target displacement of block masonry structures at near collapse performance level. The calculated target displacement by this method have been compared with the testing results of 1/4 scale model of a 10 floors block masonry structure at near collapse performance. It indicates that the present method can be used in determining target displacement of block masonry structures at near collapse performance level.更多还原
