采用薄钢板作为低层钢结构的补充剪力墙,在层中设置钢板和边界单元,与柱区分开。这种设计是为了满足加强柱的需要,因为柱子是基于抵抗自重和风荷载而设计的。这种结构引入新单元,如仅受拉杆件,以加快施工及执行承载力设计原则(如后强度上限)。采用分层流程图和简化分析模型设计结构原型,并通过大比例试验分析其性能。这种结构具有稳定的滞回性能,直到达到大的层间位移而破坏时,才出现较大的强度退化。建立准确的有限元模型,分析试验中结构的相应性能,模拟结果与试验结果吻合较好,验证了这种结构的有效性。
The use of thin steel plate as a low-rise steel structure of the additional shear wall, set in the layer of steel and boundary elements, separated from the column. This design is designed to meet the needs of reinforced columns because the columns are designed based on resistance to dead weight and wind loads. This structure introduces new elements, such as tension members only, to speed up construction and implement design principles of bearing capacity (eg, upper strength limit). The layered prototype and simplified analysis model are used to design the prototype of the structure, and its performance is analyzed through large-scale test. This structure has a stable hysteretic behavior until it reaches a large layer of displacement and destruction, only when a greater strength degradation. The accurate finite element model is established and the corresponding performance of the structure in the test is analyzed. The simulation results are in good agreement with the experimental results, which verifies the effectiveness of the structure.
