中文摘要：

在试验的基础上提出了适用于火灾后型钢混凝土异形柱（包括＋形、T形、DL形和BL形）偏心受压时正截面承载力计算的折算截面法：首先将截面在计算方向上折合成相应的柱状截面，然后按仅考虑两对边型钢的单向偏压计算公式计算相应方向上的正截面承载力，同时计算时要考虑相应的初始偏心距和偏心距增大系数，最后对计算出的承载力通过系数进行修正。结果表明：简化计算值与试验值吻合较好。

英文摘要：

A simplified calculation method of the normal section bearing capacity for steel reinforced concrete （SRC） special-shaped columns under eccentric compression was proposed based on experimental results. Sections in the calculation direction were converted into the corresponding column type sections. Then normal section bearing capacity was calculated in the case of uniaxial eccentric compression and shaped steel of two edges on the calculation direction was considered only. Initial eccentricity and eccentricity magnification factor need to be considered. Calculation results need a factor to offset. Test results show that the simplified calculation values are good agreement with the test results.
