Abstract Resilience of structures is already the new issue and challenge in the field of earthquake engineering. In order to enhance the restorability of concrete wall panels and further use them in steel moment frames, a novel self-centering steel reinforced concrete coupled wall panels with replaceable energy dissipaters is presented in this paper. For this purpose, subassembly tests of the coupled walls with frame beams as boundary were carried out. Four full-scale specimens were tested under cyclic lateral loads. The initial prestress of post-tensioned (PT) steel bars and configuration of energy dissipaters were varied to investigate their impacts on lateral responses of the walls. The failure process, load-displacement relation, energy absorption capacity, residual deformation and force of PT steel bars were also investigated. Test results show that the three-stage nonlinear response is characterized by the sequential failure process of wall rocking, yielding of energy dissipater and yielding of PT steel bars. The initial prestress of PT steel bars greatly affects the initial stiffness, rocking load and residual deformation of the walls. Failure of the walls is mainly concentrated on the energy dissipaters. With the increase of energy dissipaters in quantitative terms or in type terms, the capacity of energy absorption is accordingly improved, but self-centering capacity is accordingly weakened.

带可更换消能器的自定心钢筋混凝土耦合墙板试验研究

摘要 结构抗力已经成为地震工程领域的新课题和新挑战。为了提高混凝土墙板的可恢复性并进一步将其用于钢力矩框架，本文提出了一种新型自定心钢筋混凝土耦合墙板和可更换耗能器。为此，对以框架梁为边界的耦合墙进行了组件测试。四个全尺寸试样在循环横向载荷下进行了测试。后张 (PT) 钢筋的初始预应力和能量耗散器的配置是不同的，以研究它们对墙体横向响应的影响。还研究了PT钢筋的破坏过程、荷载-位移关系、能量吸收能力、残余变形和受力。试验结果表明，三阶段非线性响应表现为墙体摇摆、消能器屈服和PT钢筋屈服的连续破坏过程。PT钢筋的初始预应力对墙体的初始刚度、摇摆荷载和残余变形影响很大。墙体的失效主要集中在耗能器上。随着耗能器数量或类型的增加，吸能能力相应提高，但自定心能力相应减弱。墙体的摇摆荷载和残余变形。墙体的失效主要集中在耗能器上。随着耗能器数量或类型的增加，吸能能力相应提高，但自定心能力相应减弱。墙体的摇摆荷载和残余变形。墙体的失效主要集中在耗能器上。随着耗能器数量或类型的增加，吸能能力相应提高，但自定心能力相应减弱。
