现有钢板剪力墙耐震设计规范对于多楼层钢板剪力墙边界梁柱的容量设计并无清楚交代,本研究主要目的在于针对未束制型钢板剪力墙的使用性与消能特性加以改良,并研发束制型钢板剪力墙试体,共规划四座试体,3cm厚之低降伏LYS钢板为墙体:一座完全不加束制构件,另两座试体分别在LYS钢板墙体之两面以矩型钢管束制之,第四座则以钢筋混凝土板(简称为CP板)束制LYS钢板墙,于地震工程研究中心进行试验,同时并研究钢板剪力墙的分析模型。试验结果显示,束制型钢板剪力墙,LYS钢板挫屈所产生之声响减小,且平面外侧向挫屈变形也随之减少,而消能效果也明显增加。束制与未束制钢板剪力墙之分析模型采用Strip Mod-el,皆可以准确仿真出试验所得之迟滞循环。在单向侧推分析中,采用等效层斜撑模型仿真束制型钢板剪力墙的初始劲度以及强度与试验结果接近。
The seismic design code of the existing steel plate shear walls does not give a clear account of the capacity design of beams and columns at the boundary of multi-story steel plate shear walls. The main purpose of this study is to improve the usability and energy dissipation characteristics of the uncoiled steel plate shear wall , And research and development of beam system steel plate shear wall test, planning a total of four test body, 3cm thick low-drop LYS steel for the wall: a complete beam system components, the other two were LYS steel body wall test The two sides are made of rectangular steel tube bundles, the fourth one is made of LYS steel wall reinforced with reinforced concrete slab (CP board for short), tested in seismic engineering research center, and the analysis model of steel plate shear wall is also studied. The experimental results show that the sound generated by beam-formed steel plate shear wall and LYS steel plate buckling decreases, and the out-of-plane lateral buckling deformation also decreases, while the energy dissipation effect also increases obviously. Strip Mod-el, an analytical model of beam-formed and unbent beam shear walls, accurately simulates the hysteresis loop of the test. In the one-way lateral analysis, the initial stiffness and strength of the beam-formed steel plate shear wall simulated by the equivalent layer brace model are similar to the experimental results.
