To investigate the maintenance effect of diaphragm-to-rib fatigue cracks via steel plate reinforcement, finite element models different-shaped plates were established. Stress intensity factors at crack tip before and after reinforcement obtained, variations in stresses studied. Polygonal reinforcements then carried out on a real bridge based calculation results. The changes stress amplitudes da...

general kind of encroachment of river is constructing a bridge on it. purpose of encroachment of river is occupation part of river and flood plain for constructing bridge. often being economical of bridge innovation affirmated that most of encroachment take place to river and flood plain, which this encroachment can be in form of embankment in flood plain of river or into the main bed of river ...

As the stress amplitude in anchorage zone of cable-stayed bridges vary considerably, it is essential to study fatigue-load-bearing capacity structures cable-stayed-bridge girders. In this study, mechanical properties and force-transmission mechanism a built-in double-fixed steel anchor box, as well influence geometric design parameters main pressure plates support on its performance, were studi...

Purpose: The aim of this work is the construction bridge structures on a soil foundation with physical and mechanical characteristics, often differing from survey activity parameters. Technical regulations supports envisage plate-bearing test drilled pile foot. Design/methodology/approach: quality improvement not only preparation, but also requirements for structural reliability, approximated R...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...
