摘要

为研究新型保温夹芯剪力墙在格构式角钢约束下两侧混凝土的协同工作性能、承载力以及抗震性能,对三片剪力墙足尺模型进行水平低周反复荷载作用下的试验,并对剪力墙的延性、滞回性能、耗能性能进行了分析。结果表明:两侧混凝土在现有斜插筋的拉结作用下能够较好地协同工作;角钢能够对墙板有效约束;墙板在达到极限承载力后,强度、抗剪刚度下降较快,易发生剪切滑移;角板能较好的提高墙体耗能、抗滑移能力。并根据试验结果提出提高延性能力的措施,为设计计算提供依据。
Three full-scale models for a new sandwich wall were tested under low cyclic loading so as to study their bearing capacity and seismic behavior,and collaborative work performance of concrete layers on both sides of the wall.Ductility,hysteretic behavior and energy dissipation of the wall were also analyzed.Results were as follows: concrete layers on both sides worked collaboratively under diagonal bars;the wall could be constrained by angle iron effectively;after the wall reached the limit state,its strength and shear stiffness decreased rapidly,and the wall was prone to shear slip;and corner plate could improve anti-sliding capacity of the wall.Some measures to improve ductility of this wall were presented according to the experimental results,which provided a reference for design.
