The unique structural design of an arch ring featuring varying inclination angles for individual segments causes variations in the longitudinal distribution temperature field d along axis. This study aims to enhance understanding fields reinforced concrete (RC) bridges with diverse configurations during their construction phases. A comprehensive investigation into three-dimensional pattern solar-induced within ribs RC ribbed was conducted. test specifically measuring across rib...
In the context of reinforced concrete (RC) arch bridges, while incorporation full sections steel fibers can enhance bridge’s toughness, cracking resilience, and bearing capacity, achieving an optimal balance between structural performance economic viability in this manner remains challenging. This article introduces a novel computational approach—the distributed fiber (LSFRC) arch—which considers spatial distribution damage RC arches. The static SFRC elements LSFRC beams was compared...
To control the level of tensile stress in section reinforced concrete arch cantilever construction, a construction method temporary prestressing reinforcement is proposed this study. The influence law on ring revealed based engineering background (Shatuo Special Bridge Guizhou). Meanwhile, test carried out main to verify effectiveness method. results show that configuration during suspension bridge has obvious stress. can also effectively improve force uniformity buckle cables, reduce...
In light of the limited research on latent damages during construction large-span suspension arches, this study introduced a method to simulate structural damage utilizing random porosity. Initially, based data from real-world engineering projects, most susceptible areas within arch structure were pinpointed. Subsequently, multiple test simulation models constructed. Employing Python, commands for porosity implemented ABAQUS and distinct mesh modules devised depict structures under varying...
As important load-bearing structures, suspension cables have been widely used in bridges, engineering ropeways, cable systems and other special equipment. Their dynamic problems always a research hotspot. Especially for complex such as ropeways lifting equipment, there will be moving loads acting on multi-span continuous friction-slip resulting nonlinear coupled vibration. Therefore, few scholars studied how to calculate the coupling vibration effect between considering friction slip. this...
Abstract During the cantilever casting process of reinforced concrete arch bridges with cast‐in‐situ method, it is difficult to select representative training samples for reliability analysis due its complex structural system. Many random variables and large computational sample size, this paper proposes solve indexes based on combination improved sparrow search algorithm (LGSSA) support vector regression (SVR) method. Firstly, are selected according actual situation bridge structure. Then...
The catenary cable element has more advantages than other nonlinear truss elements but is less used in commercial programs. In this paper, the initial geometric configuration of solved iteratively by dichotomous method. Then Updated Lagrangian (UL) Formulation for two-node combined with secondary development tool provided ANSYS platform-User Programmable Features (UPFs) to develop a three- dimensional element—user101. algorithm and procedure paper are verified through examples real bridge....
