| 摘 要： | 简支转连续桥梁受温度影响时,结构将产生内力重分布现象。目前有限元方法几乎成为简支转连续梁桥温度效应计算的唯一手段。针对简支转连续结构体系特点,根据结构力学推导计算,得到温度效应通用计算公式,为该类结构的设计计算提供理论参考。

| Abstract: | Owing to the temperature influence,the structure of simple-continuous bridge will produce internal force redistribution.Presently,the finite-element method is nearly the only way to solve it.Aiming at the system characteristics of simple-continuous bridge,based on classical mechanics computation theory,this paper deduces the universal calculation equation of temperature internal force of simple-continuous bridge as the theory of design. |
