| 摘 要： | 基于ABAQUS软件,建立了矩形钢管混凝土双向压弯构件的三维实体有限元模型,进行了荷载-变形曲线的全过程数值模拟,理论模型得到了实验结果的验证。基于此模型,进行了矩形钢管混凝土双向压弯构件力学性能的影响因素分析,讨论了荷载偏心角、含钢率、约束效应系数、混凝土及钢材强度等参数对其力学性能的影响规律。本文结论可为进一步研究矩形双向压弯构件的实用设计方法提供参考。

| Abstract: | A 3-D finite element model was established for concrete-filled rectangular steel tube members under the bi-eccentric loading by ABAQUS software.The load versus deformation curves are calculated by the model.The results from the model are match well with the experimental results.Some parameters,such as the load eccentric angle,steel ratio,confinement coefficient,concrete and steel strength,etc.,are analyzed.The results are reference to develop the practical design method for concrete-filled rectangular steel tube members under the bi-eccentric loading. |
