摘要
根据中高层密肋复合墙体结构的特点,提出了基于位移延性的设计方法。根据计算结果,分析了内墙板配混凝土率、内墙板纵向配筋率、边框柱截面高度及墙体高宽比对密肋复合墙体位移延性的影响,其中,配混凝土率、边框柱截面高度对位移延性的影响较大,纵向配筋率的影响较小。结合工程实际提出了中高层密肋复合墙体的轴压比限值,方便了该结构体系的工程应用。
Based on the properlies of moderate-high-rise multi-bibbed composite wall structure, displacement ductility design method is investigated. It is analyzed that the effects of the concrete ratio and longitudinal steel ratio of internal slab, section depth of side frame column and the height-width ratio of wall on the displacement ductility of composite wall according to calculation results, the concrete ratio and section depth of side frame column have more influence on displacement ductility of structure and longitudinal steel ratio is little. Finally, reference to the practice, limit value of the axial compression ratio of composite wall is suggested, the result can be applied to the structure design.
