摘　　要：以往的试验研究表明,砌体填充墙的存在较大地提高了框架结构的水平承载力和侧向刚度,砌体填充墙框架水平承载力计算时应考虑砌体填充墙的影响。视砌体填充墙框架的极限水平承载力由砌体填充墙和框架共同承担,并适当考虑砌体填充墙和框架间的相互作用,侧向荷载作用下砌体填充墙等效为一根铰接于框架平面的斜压杆。据此建立砌体填充墙框架结构水平承载力的简化计算模型,提出了填充墙框架水平承载力的简化计算公式,计算值与试验值比较吻合。Previous researches indicated that the masonry infill wall enhanced the lateral stiffness and the horizontal bearing capacity of reinforced concrete frames, and the influence of masonry in- fill wall should be taken into account when calculating the horizontal bearing capacity. We sup- posed that the horizontal bearing capacity of masonry infilled reinforced concrete frame was shared by the wall and frame, the interaction between the masonry infill wall and frame was con- sidered, and the masonry infill wall was equivalent to a hinged frame plane inclined strut under lateral loads. We established the simplified calculation model of horizontal bearing capacity ac- cordingly, and proposed the horizontal bearing capacity simplified formula. The calculated value is consistent with the experimental value.
