异形柱和短肢剪力墙的轴压比限值比较分析
Comparative analysis on the axial compression ratio limit of the special-shape column and the short-shear wall
【摘要】 通过对异形柱轴压比限值影响因素的分析,根据大小偏心受压界限破坏机理,分别讨论了异形柱轴压比随截面尺寸、纵筋配筋率变化的规律,建议T形、L形柱腹板纵筋取为翼缘纵筋的0.7~1倍之间,并给出了此条件下的异形柱轴压比限值;依据异形柱轴压比限值的研究结论,参照高规对短肢剪力墙轴压比限值的规定,对比分析了异形柱和短肢剪力墙的轴压比限值,得出了异形柱和短肢剪力墙的轴压比限值可取一致的结论.
【Abstract】 Through an analysis on the influence of the axial compression ratio limit of the special-shaped columns,the paper studied the influence of the sectional dimension and reinforcement ratio on the regulaty of special-shaped columns,and proposed the reinforcement ratio of the flange and the web as 0.7~1.The axial compression ratio limit on this condision was given. Acording to the conclusion and the provision of the technical specification for concrete structures of tall building about the axial compression ratio limit of the short-shear wall,their axial compression ratio limits has been compared.The conclusion is that the axial compression ratio limits of the short-shear wall could be consistent with that of the special-shaped columns.
【Key words】 special-shaped column; the short-shear wall; axial compression ratio limit; the sectional dimension; ratio of reinforcement;
