摘 要: 基于强度叠加理论和变角度空间桁架模型,通过对型钢混凝土构件极限承载力的理论推导及对数值结果的回归分析,首次提出极限承载力计算公式的修正系数。通过将修正前、修正后的计算值与模拟值(试验值)进行对比分析,最终验证了修正系数的准确性及修正后极限承载力计算公式的合理性。
关 键 词: 土木建筑结构;型钢混凝土试件;纯扭作用;极限承载力

Abstract: Based on the strength superposition theory and variable angle space truss model, the theoretical derivation and the regression analysis of numerical results of ultimate bearing capacity of profile steel concrete components were carried out. The correction coefficient of the formula for calculating ultimate bearing capacity is put forward for the first time. By comparing the calculated values before and after correcting with the simulation values (test values), the accuracy of the correction factor and the rationality of the formula for calculating the ultimate bearing capacity are finally verified.
Key words: civil engineering structure; profile steel concrete specimen; pure torsion; ultimate bearing capacity
