摘　　要：为研究型钢混凝土复合受扭构件的滞回性能,试验考虑了轴压比、混凝土强度、扭弯比和配箍率对型钢混凝土柱复合受扭滞回性能的影响,研究了5个1/2比例的十字型钢混凝土柱在低周反复荷载作用下的复合受扭性能,同时,还与1个钢筋混凝土复合受扭柱进行了对比试验。并采用ABAQUS软件对试验全过程进行了数值模拟,发现,模拟结果与试验结果基本吻合,证明了用本文有限元分析方法来研究型钢混凝土构件的受扭性能是可行的。In order to study hysteretic behavior for steel encased concrete members subjected to combined torsion, the combined torsion tests of 5 half scale steel reinforce concrete（SRC） columns were conducted under low cyclic loading. The influence of the axial compression ratio, the concrete strength, torsion-bending ratio and stirrup rate on combined torsional hysteretic behavior of SRC columns are taken into consideration. Comparative analysis of a reinforced concrete column is conducted. Based on the tests results, the finite element analysis on this subject is conducted by ABAQUS, which shows that the results of test and simulation are very close to each other, proving the feasiblity of the finite element analysis in the research of torsional performance of SRC structure.
