【摘要】 在柱截面界限破坏条件下对芯柱可提高的轴压比进行了公式推导和计算。讨论了芯柱配筋率、混凝土强度等级和纵筋类别等因素的影响。对芯柱可提高的轴压比限值提出了设计建议值。更多还原

【Abstract】 The formulae of improving limit values of axial compressive ratio by the core column according to bound failure condition of column crosssection are derived and calculated.Analyze the influences of core column′s bar ratio、strength of concrete、longitudinal reinforcement classification etc are analyzed. Finally, some suggestions of design of improving limit values of axial compressive ratio by the core column are proposed.更多还原
