摘要

可替换剪切耗能梁段作为与偏心支撑钢框架分离设计的独立耗能部件,不仅能在大震发生时将结构的塑性变形局限在耗能梁段区域内,更重要的是可以方便震后对结构的修复。文中制作了3榀该钢框架结构的缩尺模型,并对其进行了单向振动台试验,得到了结构的动力特性、塑性发展情况及破坏机理,并对模型的应力分布、位移响应、加速度响应等进行了分析研究。结果表明:该模型具备良好的耗能性能,剪切耗能梁段与防屈曲支撑构件分批耗能使得结构在地震作用下有较好的抗震性;带有可替换剪切耗能梁段的防屈曲偏心支撑钢框架构件的最大层间位移角符合规范要求,并且拥有良好的安全和强度储备;结构的变形以剪切变形为主,各层间剪力增幅相对均衡,且结构具有优良的抗震性能,大震下可降低多层结构的加速度放大系数, 有效减小结构的动力响应。

Abstract

As an independent energy-dissipating component designed separately from the eccentrically braced steel frame, the replaceable shear links not only confine the plastic deformation of the structure to the region of the energy-dissipating links during large earthquakes, but also, more importantly, facilitate the repair of the structure after the earthquake. In this paper, three scaled models of this steel frame structure were fabricated and unidirectional shaking table tests were conducted to obtain the dynamic characteristics, plastic development and damage mechanism of the structure, and the stress distribution, displacement response and acceleration response of the model were analysed and studied. The results show that the specimen has good energy dissipation performance, and the sequential energy dissipation of shear links and buckling-restrained brace members makes the structure have good seismic performance under earthquake. The maximum inter-story drift angle of the buckling-restrained eccentrically braced steel frame specimen with replaceable shear links meets the requirements of the code, and it has a good safety as well as strength reserve. The structural deformation is mainly dominated by shear deformation, and the increase of shear force in each layer is relatively balanced, and it has excellent seismic performance. The acceleration amplification factor of the multi-story structure can be reduced under large earthquakes to effectively reduce the dynamic response of the structure.
