摘要:
由于现有的钢框筒结构 (SFTS)存在延性和耗能差的问题而导致该结构抗震性能不足，并且该结构还存在震后修复困难的问题，提出了带可更换耗能梁段的钢框筒结构 (SFTS-SL)，耗能梁段采用双槽钢腹板螺栓连接的形式.在SFTS-SL中，双槽钢截面可更换耗能梁段布置于裙梁的跨中，在地震作用下以通过耗能梁段的剪切变形耗散地震能量. 本文设计了SFTS和SFTS-SL结构算例，并从中选取了三个子结构建立了有限元模型，通过非线性数值分析研究其抗震性能. 结果显示，与SFTS相比，SFTS-SL在弹性抗侧刚度方面表现相似，但具有更好的延性和耗能能力；SFTSSL极限承载力略低于SFTS；SFTS-SL能够将塑性变形集中于可更换的耗能梁段，而其余构件基本处于弹性状态，有利于震后结构功能的快速恢复.
Abstract:
Due to the poor ductility and energy dissipation of the existing steel frame-tube structure (SFTS), the seismic performance of the structure is insufficient, and it also presents difficulties for post-earthquake repair. A proposed solution is to introduce a steel frame-tube structure with a replaceable shear link (SFTS-SL). The shear link is connected using double-channel steel web bolts. This paper presents design examples of both SFTS and SFTS-SL structures, selecting three substructures from each example and establishing the finite element model. Seismic performance is studied by nonlinear numerical analysis, revealing similar elastic lateral stiffness between SFTS-SL and SFTS. Although the ultimate bearing capacity of SFTS-SL is slightly lower, its ductility and energy dissipation capacity are superior. Compared with SFTS, SFTS-SL can concentrate plastic deformation on the energy dissipation beam section, while the remaining components remain in an elastic state, facilitating structural function restoration by replacing the damaged energy dissipation beam section.
