To the 36 meters crane girder with trapezoidal variable cross-section in a steel plant, finite element model is established reasonably according its actual size. The calculation of crane girder structure was introduced by using the finite element analysis software ANSYS. The local stress state of the cross-section is investigated and the stress concentration position of variable cross-section i...

This paper investigates the analytical results of seismic response multi-span prestressed concrete (PSC) I-girder bridges under loads. To perform numerical analyses, a three-span PSC bridge with width 12 m, total length 100 and maximum span 40 m was modeled, virtual location selected to consider soil properties area where constructed. The load acting on applied in consideration around pier wave...

Abstract: Based on the characteristics of box girder with corrugated steel webs, the existing prestressing force, the effect of shear deformation of composite girder on the deflection, “folding effect” in longitudinal direction of corrugate steel webs and the arrangement of external tendons were considered comprehensively. With the experiment results of five literatures integrated, N/fcA (the a...

To study the mapping relationship between girder deformation and rail for CRTS Ⅲ slab ballastless track (SBT) multi-span simply supported bridge, this derived a simplified analytical solution, corresponding ANSYS finite element model (AFEM) was established. Compared with fine (FAM) AFEM, calculation results of three models under conditions pier settlement vertical fault were compared, which ver...

In this article on increasing the efficiency of steel combined structures, tasks rational design, regulation and control structural parameters elements, use steels with increased mechanical properties are considered. It is shown that for a six-span stiffening girder truss elastic supports, which operates under distributed load, moment 72 times smaller than single-span beam. suggested to high-st...

The analysis based on an ideal state as well as the simulation and control to reach it are common issues in the design and construction of a cable-stayed bridge. For a long-span cable-stayed bridge, the huge initial stress accumulated in the pylon and the girder will reduce the overall structure stiffness. Thus, the live load evaluation employing influence lines, which is based on the Muller-Br...
