摘要

摘要: 为了研究可恢复功能结构抗震性能和耗能构件简化建模方法,基于传统刚接钢框架提出了一种新型装配式自复位钢支撑结构体系,该体系在传统刚接框架中附加了可更换构件(双屈服点装配式防屈曲支撑、带狗骨削弱盖板的自复位预应力钢框架梁柱节点)。通过有限元软件OpenSEES建立了可更换构件简化计算模型,与既有数据对比验证了简化模型的正确性。基于所提出的抗震性能化设计目标设计了新型装配式体系并通过弹塑性时程分析(NLTHA)研究了新型体系的抗震性能。研究表明:所提出的简化计算模型具有较高的精度,可以应用于体系的弹塑性时程分析中;基于所提出的抗震性能化指标设计的新型装配式体系较传统体系抗震性能优越,新型装配式体系的最大顶层位移和最大层间位移角均小于传统刚接钢框架结构体系与传统刚接钢支撑结构体系,其x、y向的最大顶层位移和最大层间位移角较传统刚接钢框架结构体系分别平均减少28.35%、10.13%和26.86%、10.42%;双屈服点装配式防屈曲支撑能够控制结构层间变形,带狗骨削弱盖板的自复位预应力钢框架梁柱节点的加入能够进一步提高其耗能能力。

Abstract: To investigate the seismic performance of self-centering structural systems and the simplified modeling methods for energy-dissipating components, the paper proposed a novel prefabricated self-centering steel frame-support system based on traditional rigid-frame steel structures. This system incorporates replaceable components, including double-yield-point prefabricated buckling-restrained braces and self-centering prestressed steel frame beam-column joints with dog-bone weakened cover plates, into the traditional rigid-frame structure. A simplified calculation model for the replaceable components was developed by using the finite element software OpenSEES, and its accuracy was verified through a comparison with existing data. Based on the proposed seismic performance-based design objectives, the novel system was designed and its seismic performance was studied through elastic-plastic time-history analysis (NLTHA). The study indicated that the proposed simplified calculation model had high accuracy and could be applied to the elastic-plastic time history analysis of the system. The novel prefabricated system, designed based on the proposed seismic performance indicators, exhibited superior seismic performance compared to traditional systems. The maximum top-floor displacement and maximum inter-story drift of the novel prefabricated system were smaller than those of both the traditional rigid-frame steel structure and the traditional rigid-frame steel bracing structure. Specifically, the maximum top-floor displacements and maximum inter-story drifts in the x-and y-directions were, on average, reduced by 28.35%, 10.13%, and 26.86%, 10.42%, respectively, compared to the traditional rigid-frame steel structure. The double-yield-point prefabricated buckling-restrained braces could control the inter-story drift of the structure, while the inclusion of self-centering prestressed steel frame beam-column joints with dog-bone weakened cover plates could further enhance its energy dissipation capacity.
