组合荷载作用下钢管混凝土构件的性能分析 |

摘 要: | 研究了薄壁钢管混凝土构件在组合荷载如压扭,弯扭,压力、弯曲和扭转作用下的性能。采用ABAQUS软件进行有限元分析,对比发现,模型的计算结果与试验一致。采用该模型对在如压扭、弯扭、压弯扭等组合荷载下影响构件极限强度的重要参数进行研究分析。参数研究有利于今后推导计算复合构件在组合荷载作用下极限强度的公式。

Abstract: | In practice, concrete-filled steel tubes (CFST) are often subjected to torsion. To date, such a problem however has not been addressed satisfactorily by design codes. The present study is thus an attempt to study the torsional behaviours of concrete-filled thin-walled steel tubes. ABAQUS software is used in this paper for the finite element analysis (FEA) of CFST subjected to pure torsion. A comparison of results calculated using this modelling shows good agreement with test results. The FEA modelling was u... |
