【摘要】 以广佛高速公路某跨线桥为工程背景,根据不同的规范计算该连续梁桥的日照温度效应,分析比较各规范计算结果之间的差异,得出等截面连续箱梁在日照温差荷载作用下温度应力的分布规律,并提出温度束概念,为解决温度效应问题提供一定的理论依据。更多还原

【Abstract】 Based on one flying bridge in the Guang-Fo highway,it analyzes the difference among every standard calculation result according to the different standard calculation of the sunlight temperature effect,gets the distribution regularities of the temperature stress acted by sunlight temperature head,and brings forward the conception of the temperature beam,which will supply given theory to solve the temperature effect problem.更多还原
