摘要

摘要: U形钢板消能器是一种能适应大位移的弯曲屈服型消能器。通过两个U形钢板消能器的拟静力试验,验证消能器具有良好稳定的耗能能力和变形能力。在此基础上,为研究减震外挂墙板对主体结构抗震性能的影响,设计并制作了一榀足尺含减震外挂墙板装配式混凝土剪力墙试件。试件中外挂墙板采用预制混凝土夹芯保温板,墙板顶部与连梁采用双排钢筋线连接(避开梁端塑性铰区),墙板底部设置U形钢板消能器并通过螺栓与基础相连。对其进行了拟静力试验研究,结果表明:U形钢板消能器在较小位移时率先屈服,此后墙肢根部和连梁端部相继出现塑性铰,最后梁端和剪力墙墙肢根部塑性铰区混凝土压碎,能够形成梁铰屈服机制;U形钢板消能器变形较为理想,符合预期的履带式滚动变形;试件滞回环较为饱满,具有良好的耗能能力和变形能力。

Abstract: U-shaped steel plate damper is a kind of bending yield energy dissipater which can adapt to large displacement. Firstly, two U-shaped steel dampers were designed and manufactured, and the quasi-static test was carried out. The results showed that the dampers had good and stable energy dissipation capacity and deformation capacity. Based on this, in order to study the effect of the facade panel with damper on the seismic behavior of the main structure, a full-scale prefabricated concrete shear wall specimen with this kind of panel was designed and fabricated. Precast concrete sandwich panel was used for facade panel, and double-row reinforcement was employed to connect the top of the panel with the coupling beam, avoiding the plastic hinge region. U-shaped steel plate dampers were connected with the foundation at the bottom of the panel by bolts. Quasi-static test was carried out for the specimen, and the test results indicated that the U-shaped steel plate dampers yielded first when the displacement was quite small, then plastic hinges appeared successively at the root of wall and the end of coupling beam, and finally, the concrete in the plastic hinge area crushed; the beam hinge mechanism could be achieved; the U-shaped steel plate dampers had ideal crawler rolling deformation manner which could meet the expectation; the hysteresis loop of the specimen was relatively full, and the specimen had good energy dissipation and deformation capacity.
