The ballastless plate girder bridge, classified as a structure type that requires an emergent replacement among domestic railway bridges, generally tends to upgrade ballasted track along with continuous welded rail (CWR). axial forces of the CWR due temperature change need be distributed bridge foundations. Because most existing bridges over 50 years age do not provide any design information, s...

Abstract Many existing historical masonry arch bridges used in the road and railway networks are still service. However, most of them show a structural performance deficit due to several factors. This study deals with seismic behavior assessment an three‐arched bridge through nonlinear, non‐adaptive static analysis carried out by three‐dimensional Finite Element model. Input data were collected...

A dynamic computational program considering slip, shear-lag and time-dependent effects of composite box-girder bridge–train coupling system is firstly proposed based on the authors’ previous studies. In program, long-term vertical displacement a bridge calculated. The calculated then superimposed existing uneven track as new excitation to obtain responses system. 3 × 40 m simply supported steel...

The concept of designing sacrificial elements to dissipate seismic energy while preserving the integrity of the structure’s other main components is known as the structural fuse concept. Few implementations of the structural fuse concept have been rigorous in emphasizing easy and complete replaceability of the sacrificial elements and absence of damage to the primary load-resisting structural s...

Optimum tendon layout of prefabricated prestressed concrete beams was an early application of design optimization methodologies. However, most of the approaches found in the literature were not suitable to be implemented in real life bridge engineering. To fill the existing gap research has been conducted in past years by the authors to optimize prefabricated concrete beams formulating the prob...

To implement steel bridge maintenance, especially that related to fatigue damage, it is important to monitor bridge deformations under traffic conditions. Bridges deform and rotate differently under traffic load conditions because their structures differ in terms of length and flexibility. Such monitoring enables the identification of the cause of stress concentrations that cause fatigue damage...

The streamline flat steel box girder is broadly used in long span cablesupported bridges all over the world. As one of the most important part of the bridges, its stress level and distribution under various dynamic loads are especially concerned. However, it is difficult to obtain the accurate stress of the steel box girder by common finite element (FE) calculation. The Runyang Suspension Bridg...

Based on an actual corrugated steel plate arch bridge, considering soil-structure interaction, by using the finite element program of ANSYS, a 2-D finite element model was set up to analyze the soil pressure and structural deformation under different load conditions in detail. Since this type of structure relies on the soil-structure interaction to share the load, as the structural parameters h...

Microalloyed S355N steel plates are extensively used in bridge and high-rise building structures. One of the factors affecting the mechanical properties is the size and morphology of inclusions. In this research, microalloyed S355N steel plates with different sizes of inclusions were examined. One contained long manganese sulfide inclusions (LI material) and the other had short ones (SI materia...
