摘　　要：在钢纤维高强混凝土薄壁箱梁纯扭试验研究的基础上,利用ANSYS软件对试验构件进行了全过程分析,并与试验进行了对比验证.结果表明,ANSYS软件分析结果与试验结果吻合较好,证实了ANSYS软件可以较好地用来模拟钢纤维高强混凝土薄壁箱梁的受力-变形全过程,为ANSYS软件在后续研究工作中的应用提供了可靠依据.在此基础上,对试验构件在各级扭矩作用下,沿跨度方向各截面的线扭转角与畸变角进行了计算分析,得到了线扭转角与畸变角在构件受力-变形全过程中沿跨度方向的变化规律.Based on the research of the reinforced steel fiber high-strength concrete thin-walled box girder with pure torsion,compareing with the data of experiment, the full ranger of torsional of the specimen has been studied by ANSYS program. The results show that both of them are accordant and verify that ANSYS program can figure out the full ranger of torsional of the reinforced steel fiber high-strength concrete thin- walled box girder better,which offer reliable data in further research. The linear torsion angle and distortion angle of Specimen performed under different torsion levels, which is in different sections and along the span of the girder is calculated by ANSYS program. The results demonstrate the rule that the linear torsion angle and distortion angle along the span of the girder is varying.
