首发时间:2017-04-28
摘要:基于强度叠加理论和变角度空间桁架模型,对型钢混凝土构件极限承载力进行理论推导以及对数值结果的回归分析,首次提出了极限承载力计算公式的修正系数。通过将修正前、修正后的计算值与数值模拟值(试验值)进行对比分析,最终验证了修正系数的准确性以及修正后极限承载力计算公式的合理性。

Calculation of Ultimate Bearing Capacity of Profile Steel Concrete Specimens Under Pure Torsion
Abstract:Based on the strength superposition theory and variable angle space truss model, the ultimate bearing capacity of profile steel concrete members was carried out theoretical derivation and the regression analysis of numerical results. 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 the correction with the numerical simulation values (test values), Finally, the accuracy of the correction factor and the rationality of the formula for calculating the ultimate bearing capacity are verified.
