摘要:
为研究火灾下预应力混凝土多梁肋T型结构翘曲形态,建立了梁肋单侧火灾下预应力混凝土多梁肋T型结构的火灾模型,给出了翘曲计算方法,采用ANSYS分析了梁肋单侧火灾下预应力混凝土多梁肋T型结构翘曲规律。研究结果表明:边肋外侧受火时,边肋在四分点的横桥向凸翘显著,沿纵桥向翘曲呈W型,桥面板呈单侧翼缘板翘曲或双侧翼缘板翘曲形态;边中肋间受火时,梁肋横桥向翘曲呈V型,翘曲值大;中肋间受火时,梁肋横桥向翘曲呈倒W型,桥面板形成受火区鼓包形态;所得结论可为预应力混凝土多梁肋T型结构火灾后评估提供科学依据。
Abstract:
In order to study the shape of buckling for pre-stressed concrete multi-beam Tshaped structure exposed to fire, the fire model for pre-stressed concrete multi-beam Tshaped structure exposed to unilateral fire was proposed, and the buckling calculation method was put forward. Moreover, the buckling law for pre-stressed concrete multi-beam Tshaped structure exposed to unilateral fire of girder was analyzed by ANSYS. The study results indicate that when bias girder is exposed to unilateral fire, transverse buckling of girder at quartile is obvious, it presents Wshape along longitudinal bridge span, deck presents a shape of buckling for single flange plate or double flange plates. Transverse buckling of girder presents Vshape when girder exposed to fire between bias and middle girders, its buckling value is high. Transverse buckling of girder presents a reversed Wshape when girder exposed to fire between middle girders, deck presents a convex shape. The obtained conclusion can provide scientific reference for estimating the pre-stressed concrete multi-beam Tshaped structure after fire.
