本文通过对一般多层钢筋混凝土框架房屋的砖填充墙震害现象的研究分析,提出了砖填充墙在框架房屋抗震设计中几个主要问题(基本周期计算,楼层地震剪力分配原则、框架柱附加作用力计算以及抗震构造措施等)的初步意见,不妥之处请批评指正。砖填充墙对框架房屋的基本周期计算的影响问题,实质上是对砖填充墙的刚度计算以及在抗震计算中如何取值问题。目前国内有些资料提出了近似计算方法;

In this paper, through the research and analysis of the damage phenomenon of brick-infilled wall in general multi-story reinforced concrete frame buildings, some major problems in the seismic design of framed buildings with brick infill walls are proposed (basic period calculation, floor seismic shear distribution principle, frame column The preliminary opinions on additional force calculations and measures for seismic structures, etc., are not correct, please criticize and correct me. The problem of the influence of the brick-filled wall on the basic cycle calculation of the frame house is essentially the calculation of the stiffness of the brick-infilled wall and how to take the value in the seismic calculation. At present, some domestic data suggest approximate calculation methods;
