【摘要】：提出了一種適用于梁貫通式支撐鋼框架的自復(fù)位支撐模塊,為結(jié)構(gòu)提供抗側(cè)剛度、自復(fù)位剛度和耗能能力,使得結(jié)構(gòu)在震后無殘余變形,更換支撐后即可使用。該模塊由水平邊緣構(gòu)件(HBE)、豎向邊緣構(gòu)件(VBE)、預(yù)應(yīng)力鋼絞線、鉸接柱和柔性支撐組成,其自復(fù)位剛度由沿HBE布置,錨固在VBE翼緣外側(cè)的預(yù)應(yīng)力鋼絞線提供。該模塊可在工廠預(yù)制,現(xiàn)場用高強螺栓與框架梁連接,便于施工。用有限元軟件ABAQUS6.11對該模塊進行了精細化建模分析,并詳細解釋了分析結(jié)果。建立7個有限元模型進行參數(shù)分析,表明預(yù)應(yīng)力鋼絞線的數(shù)量、初始預(yù)拉力的大小和支撐的橫截面積對模塊的剛度及耗能能力有較大影響。
[Abstract]:This paper presents a self-reset support module suitable for beam through braced steel frame, which can provide lateral stiffness, self-reset stiffness and energy dissipation ability for the structure, so that the structure has no residual deformation after the earthquake, and can be used after the replacement of the bracing. The module is composed of horizontal edge member, vertical edge member, prestressed steel strand, hinged column and flexible support. Its self-reset stiffness is provided by prestressed strand arranged along HBE and anchored on the outside of VBE flange. The module can be prefabricated in the factory and connected with frame beam by high-strength bolt, which is convenient for construction. The finite element software ABAQUS6.11 is used to analyze the model in detail, and the results are explained in detail. The parameter analysis of seven finite element models shows that the number of prestressed steel strands, the size of initial pretension force and the cross-sectional area of braces have great influence on the stiffness and energy dissipation capacity of the modules.
