读取特征值,0.060,说明：,"1,本表已经考虑了特一级、一、二、三、四级柱的最小构造体积配箍率0.8%、0.8%、0.6%、0.4%、0.4%",,,,,,,,C80,35.90,2.22,38000,,,,,

砼强度等级,C40,,,,,,,,,,,,,,,,,,

砼抗压强度,19.1,,2，本表已经考虑了砼强度小于C35和钢箍强度大于360的情况处理。,,,,,,,,,,,,,,,,

箍筋等级,HPB300,,3，剪跨比不大于2的柱取右列数值,,,9度时为,1.50%,9度以下为,1.20%,,,,,,,,,,

箍筋强度,270,,4，框支柱取右格中的数值,,,错误,,,,,,,,,,,,,

计算配箍率,0.42%,,5，计算λV的过程数据是根据轴压比、抗震等级、箍筋形式来求λV的。当轴压比超出表中数值时计算没有意义。,,,,,,,,,,,,,,,,

,,,,,,,,,,,,,,,,,,,,

,,,6，本表上下两部分是相互独立的，上部的表只求出某根柱的体积配箍率。下部是求实际配箍的体积配箍率。然后用户自己比较取用。,,,,,,,,,,,,,,,,
