【摘要】 相比传统钢筋混凝土剪力墙而言,内置钢板可以使钢筋混凝土墙体轴压承载力得到大幅提高,而外层的钢筋混凝土结构又解决了钢板的屈曲问题。为进一步研究内置钢板剪力墙的承载特性,采用数值模拟的分析方法,从轴压比、高宽比和钢板厚度这3个主要参数出发,研究了不同参数下内置钢板剪力墙的承载特性,并采用麦夸特法和通用全局优化算法,对剪力墙的峰值承载力进行了经验公式拟合,得到综合反映轴压比、高宽比和钢板厚度的计算公式。研究成果可以为该类组合剪力墙构件形式在实际工程中的应用提供参考。更多还原

【Abstract】 Compared with the traditional reinforced concrete shear wall,the internal steel plate can improve the axial load bearing capacity of reinforced concrete wall,while the outer layer of the reinforced concrete structure has provided a way to solve the problem of plate buckling. For further study of the internal steel plate shear walls’ bearing characteristics,numerical simulation analysis,from the axial compression ratio,the aspect ratio and the thickness of the steel plate was made to study the different parameters built-bearing characteristics of steel plate shear wall. Marquardt method and the common and global optimization algorithm were used. The peak shear bearing capacity of the empirical formula fit to give a comprehensive reflection of axial compression ratio,calculated aspect ratio and plate thickness. The research results can provide reference for the application of this kind of composite shear wall structure in practical engineering.更多还原
