摘要
通过对工业厂房高强混凝土框架柱轴压比限值的分析 ,提出在高轴压下 ,确定柱受压纵筋和约束箍筋的计算公式 ,以满足对高强混凝土柱有限延性的要求 (μΔ≥ 3) ,并给出对应于不同混凝土强度等级的柱轴压比的限值 .
Analyses on the mechanics of HSC frame columns under high axial load was carried out to put up the formula for calculating the transverse and longitudinal bars in high axial compression ratio to meet the demand of deformation with HSC columns(μ Δ ≥3). Finally , the limit value of axial compression ratio of HSC frame columns in industry works is given.
