技术领域technical field
本实用新型涉及抗震结构领域，特别涉及一种连梁耗能装置。The utility model relates to the field of anti-seismic structures, in particular to a coupling beam energy dissipation device.
背景技术Background technique
传统连梁由于通常跨高比较小，在强震作用时，连梁的内力往往很大，容易产生脆性破坏，连梁破坏后，联肢剪力墙的各墙肢形成了单片悬臂墙，结构的侧向刚度大大降低，变形加大，最终可能导致结构倒塌。除此之外，传统连梁耗能效果较差，强震后不易修复或代价昂贵。近年来，部分学者开始研究在连梁跨中安装连梁耗能装置来减轻墙体的震害，在强震时，连梁耗能装置通过上下错动屈服耗能以达到减轻连梁其余部分和墙体破坏的目的，而且震后易于修复或更换。Due to the relatively small span height of the traditional coupling beam, the internal force of the coupling beam is often very large under strong earthquakes, which is prone to brittle failure. After the coupling beam is damaged, each wall of the combined shear wall forms a single piece of cantilever wall. The lateral stiffness of the structure is greatly reduced, and the deformation increases, which may eventually lead to the collapse of the structure. In addition, the energy dissipation effect of traditional coupling beams is poor, and it is difficult or expensive to repair after strong earthquakes. In recent years, some scholars have begun to study the installation of coupling beam energy-dissipating devices in the mid-span of coupling beams to reduce the earthquake damage of the wall. And the purpose of wall damage, and easy to repair or replace after the earthquake.
因此，研制开发一种既能够在强震时屈服耗能，又能够在震后易于修复或更换的连梁耗能装置就显得既迫切而且特别有意义。Therefore, it is urgent and particularly meaningful to develop a coupling beam energy dissipation device that can not only yield energy dissipation during strong earthquakes, but also be easy to repair or replace after earthquakes.
