U形肋正交异性组合桥面板构造参数分析

Analysis on Structural Parameters of U-shaped Rib Orthotropic Composite Bridge Deck

摘要:

针对U形肋+平钢板+混凝土板形成的正交异性组合桥面板，利用Ansys空间有限元软件，对组合桥面板的U形肋尺寸、U形肋间距、横隔板间距、钢顶板厚度及混凝土板厚度等主要构造参数进行研究，提出U形肋正交异性组合桥面板的合理构造尺寸，为今后设计提供了有益的参考。

Abstract:

Aiming at the orthotropic composite bridge deck formed of U-shaped rib + plain steel plate + concrete slab, Ansys spatial finite element software is used to study the main structural parameters of U-rib size, U-rib spacing, diaphragm plate spacing, steel roof thickness and concrete slab thickness. The reasonable structural dimension of U-shaped rib orthotropic composite bridge deck is proposed, which can provide the beneficial reference for the design in the future.
