The physical and mechanical properties of the reservoir bank slope deteriorate under fluctuation water level, causing debonding slippage, which can produce different degrees damage to bridge foundation, piers, superstructure, a condition that is difficult treat. In this paper, for Yangtze River Bridge instability problem in Three Gorges area, numerical model was established using finite element...

Considerable age of a very high number bridges conjointly with steadily increasing amount traffic and changes in design philosophy (e.g. earthquake engineering) have made maintenance needed retrofitting become more important over the years. Retrofitting can necessary both for flexure or shear enhancements. Existing steel solutions strengthening are laborious complex, durability construction is ...

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...

This paper presents a numerical study of the structural behaviour of concrete bridge deck slabs under static patch loads and dynamic traffic loads and an investigation of compressive membrane action (CMA) inside slabs. Those deck slabs were reinforced with Glass Fibre Reinforced Polymer (GFRP) bars. Non-linear finite element analysis (NLFEA) models were established using ABAQUS 6.10 software pa...
