摘要:
当前国家对建筑结构的抗震性能和震后功能恢复能力提出了更高要求。基于短剪切型消能梁段的受剪屈服特性和剪切扩孔型螺栓连接的受剪滑移性能,提出一种新型扩孔螺栓连接型消能梁段,可有效增大消能梁段的延性和耗能能力并同时减小消能梁段的损伤,使带扩孔螺栓连接型消能梁段的新型Y形偏心支撑结构更好地适应当前要求。采用有限元方法详细分析扩孔螺栓连接型消能梁段的滞回性能、破坏模式和耗能机理,由此得到其骨架曲线和力学模型,并阐述其力学模型的影响参数,为相应偏心支撑结构的设计和分析提供理论依据。
Abstract:
Effective improvement of the seismic performance and resilience capacity of the modern building structures is currently in higher demand to ensure the seismic safety. In this paper, a new type of very short shear link with shear slotted bolted connection (SSL-SSBC) in the Y-shaped eccentrically braced frames(Y-shaped EBF) is developed, which combines with the shear property of SSLand the friction slip of SSBC.The shear links can be capable of dissipating higher seismic energy with higher ductility and less damage, and the seismic performance and resilience capacity of Y-shaped EBF with SSL-SSBC can be further improved, sothe new Y-shapedEBF can better meet the higher demand in modern code for seismic design of buildings.The hysteresis curves, failure modes and energy dissipation mechanism of SSL-SSBC are revealed in detail by using the finite element method. The bone curves and mechanical models are proposed, and the influential parameters of the mechanical model are obtained, which can be used as theory basis for the design and analysis for Y-shaped EBFs.
