摘要
本文分别用结构整体动力计算的剪切模型和弯剪模型,对多栋高宽比不同的配筋混凝土小砌块建筑进行了大量的动力特性计算和在地震输入下的结构反应计算分析。得到的主要结论是:1.弯剪模型非常适合于中、高层配筋小砌块建筑的动力特性分析和地震反应计算;2.只有对高宽比小于1的小砌块建筑,剪切模型的计算结果才是比较可靠的。
In this paper, by using shear model and moment -shear model, the seismic responses of the several reinforced concrete masonry buildings with different high-wide ratio subjected to earthquake motion are analysed. The dynamic characteristics of the buildings are also evaluated by the two models respectively. The obtained first frequencies are compared with the frequencies given by the formulas of U. S. and China. The main conclusions are as follows:
1. The moment-shear model is an ideal model for the seismic response analysis of reinforced concrete masonry buildings.
2. The shear model can be used in analysing the seismic response of reinforced concrete masonry buildings only when the high-wide ratio of the buildings is less than 1.
