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。
Previous studies have shown that the reinforced concrete-masonry composite wall is an excellent structural form with good seismic performance and low cost. This study was conducted on the seismic performance of a reinforced concrete-masonry composite wall with 22 different aspect ratios, different vertical compressive stresses, different vertical reinforcement ratios, and different levels of reinforcement ratios, and passed through other 65 similar walls in China. The body analysis analyzes the damage characteristics of the wall under vertical and horizontal loads, the normal section bearing capacity, the oblique section bearing capacity and the seismic performance of the wall, and gives the calculation of the seismic bearing capacity of the wall. The formula can provide a reference for the design of such houses.
