摘要 型钢高强混凝土短肢剪力墙较普通钢筋混凝土短肢剪力墙具有承载力高、延性好等优点。为了研究型钢高强混凝土T形截面短肢剪力墙的正截面受力性能及不同型钢骨架形式对其性能的影响,本文通过对两个含实腹式型钢骨架和一个含桁架式型钢骨架的型钢高强混凝土T形截面短肢剪力墙试件进行正截面偏心压力作用下的试验研究,以揭示该类构件的工作机理、破坏形态和极限承载力。试验研究表明:型钢高强混凝土T形截面短肢剪力墙的破坏过程与普通短肢剪力墙相似,横截面的平均应变基本符合平截面假定,型钢与混凝土能够保持协同工作,两种配钢形式的构件受力性能差别不大。 A short shear wall with high-strength concrete and reinforce steel has higher bearing capacity and greater ductility than the ordinary one. In order to study the mechanical properties of steel-reinforced high-strength concrete T-shaped short pier shear wall and the influence of different shaped-steel layouts on the mechanical properties, an experiment of three steel reinforced high-strength concrete T-shaped short pier shear walls (including two solid web steel reinforced skeleton members and a truss steel reinforced skeleton member) under normal-section eccentric compression was carried out to reveal the working mechanism, failure patterns and the ultimate bearing capacity of the components. The results show that the failure process of steel-reinforced high-strength concrete T-shaped short pier shear wall is similar to normal short pier shear walls; the average strain of cross section of the wall accords with the plane section hypothesis; steel and concrete can work together, and these two kinds of shaped-steel layouts has little difference in mechanical behavior.
