新型哑铃形钢管混凝土拱肋极限承载力计算方法
Calculation Method of the Load-carrying Capacity of New Type Dumbbell-Shaped CFST Arch Rib
摘要
Abstract
New dumbbell-shaped concrete filled steel tube (CFST) member has been gradually applied to the bridges for its effective function in solving the blasting problem that existed in traditional dumbbell-shaped section during the construction process.While there are no relevant reports about the calculation methods on loadcarrying capacity of new dumbbell-shaped arch rib.Based on three different regulations,this paper finally proposed an appropriate method that can be used to calculate the load-carrying capacity of this new section through comparing the results of other calculation methods.And this method is certified with the design load data which is collected from a real new dumbbell-shaped arch bridge.关键词
