Abstract

The dynamic characteristics of half-through concrete-filled steel tubular (CFST) arch bridges attract broad attention due to its serious vibration problems. Statistical analysis of main design parameters and structural features of this type bridges was carried out based on design information of 158 half-through CFST arch bridges built in China, then two reference bridges were designed. The reference finite element (FE) models for half-through CFST arch bridges with thrust and those without thrust were built using Midas Civil software, then the dynamic characteristics of the two models were compared. A comprehensive parametric analysis for the dynamic characteristics of half-through CFST arch bridges without thrust was performed considering variation of rise-span ratio, aspect ratio, stiffness of arch-rib, transverse brace style, failure modes of suspenders and restriction conditions of supports. The results showed that a long-span half-through CFST arch bridge has features of dense high-order modes and obvious coupled vibration between arch rib and deck; for half-through CFST arch bridges without thrust, the main design parameters within the range of commonly used values have little influence on its dynamic characteristics; reasonable arrangement of transverse bracing and increase in width of bridge deck can significantly improve the lateral stability of structures.
