摘　　要：在研究了细长偏心受压钢筋混凝土杆件强度失效及稳定失效规律的基础上,明确了钢筋混凝土偏心压杆在考虑二阶效应和不考虑二阶效应时的非线性强度失效特征及设计准则;并通过非线性有限元模拟分析,给出了细长钢筋混凝土压杆的极限承载力表达式以及由此确定的双控设计法。On the basis of analysis of strength and stability failure rules of slender eccentrically compressed reinforced concrete member, the non-elastic strength failure character and the design criterion of slender eccentrically compressed reinforced concrete member with or without considering the second-order effect were clarified. The simulated ultimate load formula and double-control design method of slender eccentrically compressed reinforced concrete member were proposed by nonlinear finite element simulation analysis.
