In view of the fact that specification does not specify calculation model for temperature gradient concrete box-shaped arch rib without wing plates, and there is also a lack relevant research on this type rib, paper carries out impact sunshine section box flange plate based 355 m Shuiluohe Bridge. Firstly, experiment plates was conducted. According to experimental data, distribution changing rules cross-section were analyzed. Then, according measured mode vertical proposed compared with...

Abstract Although the rigid skeleton concrete arch has been widely used in engineering, research on failure mode and bearing capacity of this kind is very few, previous mostly or filled steel tube arch. To better understand mechanical properties catenary arches, three models with a span 12 m were constructed. The study focuses in-plane characteristics arches. It analyzes variation law load–displacement curve, section strain characteristics, behavior encasement, influence different loading...

In order to realistically restore the mechanical properties of arch bridge under load and damage processes, a coupled dual nonlinear analysis method is established for arch-bridge load–carrying capacity by considering effects bidirectional force transfer adaptive section stiffness. First, based on geometric theoretical transfer, macroscopic structural deformation ribs different loading conditions levels preliminarily calculated, including bending axial each arch, which used characterize...

It is difficult to calculate the buckle cable force for cantilever casting concrete arch bridge. Relying on 180 m-span Jiming Sansheng Bridge, this paper put forward one method initial based stress balance method. Firstly, equation considering only tensile was derived first time, and feasible region of calculated by allowable rib, which improved original Then, using influence matrix, optimized reducing in stages, finally optimal obtained. The practical engineering results show that it force....

In view of the limitations current code based on equivalent beam-column method with “rod mode” instead “arch for calculation concrete-filled steel tube arch bridges, this paper takes real bearing mechanism as starting point and analyzes different mechanisms eccentric pressurized column. The model test was carried out to analyze deformation state damage mode, geometric non-linear bending moment measured compared value calculated by eccentricity increase coefficient mode.” results showed that...

To investigate the reasonable range of inclination angle arch ribs, a spatial finite element method was employed based on concrete-filled steel tube (CFST) basket-handle through an bridge with span 360 m. A model established using Midas/Civil software, which verified actual data. The effects different rib angles were investigated under static loads. structural natural frequencies, linear elastic stability coefficients, internal forces, and displacements comprehensively considered to...

Yelang Lake Bridge is the largest cantilevered single‐chamber reinforced concrete arch bridge in China, with a net span of 210 m. In this article, an equation for positioning height formwork before pouring ring segment was derived, which suitable construction control long‐span such as Bridge. The elevation calculation derived under two typical working conditions that completed and buckle cable anchor tensioning are completed. addition, were evaluated. Then, new type cradle loading test...
