The invention discloses an energy dissipation structure, which relates to the technical field of steel frame supporting structure. The energy dissipation structure includes: non-energy dissipation beam, two energy dissipation beams, two supporting beams, and two frame columns; non-energy dissipation beam and two energy dissipation beams are arranged in parallel, two energy dissipation beams are connected with the two ends of the non-energy dissipation beam; two frame columns are connected with two energy dissipation beams without connecting the end of the non-energy dissipation beam; and the upper end of the two supporting beams. The bottom surfaces of the two energy dissipation beams are respectively connected, and the lower ends are respectively connected with the inner side of the two frame columns. The energy dissipation structure consists of two energy dissipation beams, and two energy dissipation beams are set at two ends of the non energy dissipation beam. When applied to long-span conditions, increasing the length of non-dissipative beam makes the position of the supporting beam tend to move to the frame column. Thus retaining a larger and complete space to avoid affecting the smooth progress of other operations. At the same time, it also reduces the space requirement of the energy dissipation structure and expands its scope of application.

技术介绍
耗能结构是一种耗能能力较强的结构体系,在钢结构建筑中设置剪切型偏心支撑,可增强建筑的抗震性能。在地震时耗能结构可出现局部剪切塑性形变,以耗散地震能量,避免建筑坍塌,是维护建筑安全必不可少的结构之一。相关技术中提供了一种耗能结构,如图1所示,该耗能结构包括:两个非耗能梁1、一个耗能梁2、两个支撑梁3、以及两个框架柱4。其中,非耗能梁1与耗能梁2平行设置,且两个非耗能梁1分别连接耗能梁2的两端;两个框架柱4分别连接两个非耗能梁1未连接耗能梁2的端部;两个支撑梁3的上端分别连接两个非耗能梁1的底面,下端分别连接两个框架柱4的内侧面。其中耗能梁2的长度具有最大临界值,以保证该偏心支撑结构为耗能结构。在地震时剪切型偏心支撑耗能梁可出现局部塑性形变,以耗散地震能量,避免建筑坍塌。在实现本专利技术的过程中,专利技术人发现相关技术至少存在以下问题:在较大跨度条件下采用相关技术中耗能结构时,由于限定了耗能梁2可实现的最大长度,因此为了满足跨度条件,只能增大非耗能梁1的长度,进而导致支撑梁3位于整体结构 ...
