Open full text 1 citations

Abstract

Based on energy principle, an analytical formula for lateral flexible stability capacity of single-rib and double-rib tied through arch bridge is presented under conservative forces and non-conservative forces.The correctness of the analytical formula is verified by two examples of finite element numerical solution, and some important structural parameters of lateral stability capacity are analyzed according to analytical formulas.The conclusions illustrate that increasing the lateral stiffness of arch rib is the most significant way for improvement of lateral stability capacity, and improving the stiffness of traverse brace and lateral stiffness of girder are conducive to greatly improvement of lateral stability capacity, and the lateral stability capacity of arch bridge with traverse brace is about 30% greater than that of arch bridge without traverse brace.
