Fibre-reinforced polymer (FRP) bars are used in concrete structural members to tackle the corrosion problem of steel bars. However, brittle rupture FRP results relatively low ductility such members. This paper numerically investigates feasibility using compression yielding (CY) block enhance bar reinforced beams. A finite element model is developed study behaviour beam adopting CY block, followed by a parametric analysis on effects material properties and geometry block. The indicate that...
The longitudinal joints on adjacent precast, prestressed box beams used in bridge construction are vulnerable to cracking. These cracks provide a direct path for water and deleterious agents enter the structural system, causing corrosion of embedded steel bars tendons. To avoid significant maintenance costs, safety concerns, or both, an innovative joint between two was designed current study. This is 6½ in. wide with roughened surfaces, filled shrinkage compensating concrete reinforced by...
The use of concrete incorporating slag is necessary due to global environmental concerns, but the decrease in durability caused by environments rich chloride ions requires more advanced mix designs, especially coastal areas. aim this study was thus assess influence addition on transport reinforced (RC) beams under sustained bending moments, considering two conditions chlorine exposure: drying–wetting cycles and soaking. results showed that diffusion coefficient (CDC) increased tension zones...
Use of precast elements in the design and construction bridges, especially for accelerated bridge (ABC), has been gaining traction to minimize impact closures resulted from cast-in-place construction. One such element being investigated is integral abutment. This eliminate need expansion joints between substructure superstructure, where penetration water deleterious agents can cause long-term performance issues. The abutment alleviates an joint by having superstructure rigidly connected...
In this study, a new dissipator was developed for bridge rocking piers to provide superior seismic energy dissipation characteristics. The proposed consists of grooved hexagonal mild steel core bar encased in buckling-resistant tube. To evaluate the structural performance dissipator, six full-scale specimens with identical cross sections but varying lengths and tube wall thicknesses were experimentally tested under cyclic loading controlled by strain fuse region. All found exhibit stable...
