摘　　要：以往的研究表明,钢筋混凝土-砖砌体组合墙是一种抗震性能好、造价低的优良结构形式。本研究通过22片不同高宽比、不同竖向压应力、不同竖向配筋率和不同水平配筋率的钢筋混凝土-砖砌体组合墙的抗震性能研究,并通过国内其它65片类似墙体的分析,对这种墙体在竖向和水平荷载作用下的破坏特征、墙体的正截面承载力、斜截面承载力及抗震性能进行了分析研究,给出了墙体抗震承载力计算公式,可为该类房屋的设计提供参考。Researches in the past have shown that composite wall made of RC and brick masonry is a fine kind of structure with good seismic performance and low cost. The experimental research in this paper was conducted on the seismic performance of 22 reinforced concrete composite walls with different ratios of height to width,axial compressive stresses and ratios of vertical and horizontal reinforcement. By comparison with the other 65 pieces of walls tested in China,detailed analyses were made on the characteristics of these walls,such as the failure features under the horizontal and vertical loads,loading capacity of normal section and bevel section and their seismic performance. Simplified formulas for calculating the seismic resistant capacity were given,which may provide a reference for the design of this type of structure.
