Structural analysis and improvement for a new form traveler in long-span cantilever-casting arch bridge

Abstract: A form traveler used in bridge construction has a great influence on the safety of the performance and alignment of bridges. As a cantilever casting segment of a bridge becomes longer and heavier, the traditional form traveler may not meet the strength and stiffness requirements, and there is a risk of collapse. This study has devised a new triangle truss form traveler and investigated the performance based on the Ye-Lang Lake arch bridge in China. Firstly, the numerical models of the form traveler were establ… Show more

“…Reinforced concrete (RC) arch bridges are widely used in China, especially in mountainous areas, because of their high structural stiffness, beautiful appearance, and economy advantage (Deng et al, 2019;Li et al, 2021). However, the performance degradation of RC structures has become acute as time goes on due to the coupling effect of the external service environment and internal materials degradation (Fu et al, 2017;Castorena-González et al, 2020;Fang, 2020).…”
