摘要

翘曲不仅是型钢中最重要的现象之一，也被认为是最复杂的现象。由于翘曲导致的法向应力集中增加，可能会影响型钢的延展性、承载能力和适用性。本研究对翘曲影响下的钢梁截面进行了模拟。利用建筑信息模型，将两个悬臂连接到相对两侧的两根柱子上，中间的钢梁-柱连接在梁上产生不同的力矩，以研究钢梁截面在翘曲作用下的行为。研究发现，应力应变关系有四组，取决于荷载强度和翘曲引起的旋转角度。

Behavior of steel beam section under warping using BIM program

Warping not only one of the most important phenomena in steel section it is also considered as the most complicated phenomena. Ductility, bearing capacity and serviceability of steel sections may affect by increasing stress concentration of the normal stresses due to warping. In the present work, simulation of steel beam section under effect of warping is studied. Two cantilevers connected to two columns in opposite sides with a middle steel beam-column connection to create different moments on the beam to investigate the behavior of steel section under warping using building information modeling. It is found that the stress strain relationship has four groups depending on the load intensity and the angle of rotation induced due to warping.
