...Sithija A. Abeysinghe, BSc (Eng); Hiran D. Yapa, BSc (Eng), PhD Concrete half-joint beams (HJB) are characterised by local reductions in the overall beam depth at the support and are ideal for structural connections. However, the beam joint region is vulnerable to deterioration and design/detailing...

... The reliability of bridges depends on load and resistance parameters, which vary with time. The variation is due to natural causes (loads, strength of material), time-related trends (growth in legal load limits), and deterioration (corrosion, fatigue). A considerable research effort was focused on the development...

... will deteriorate with time. Deterioration can lead to reduction in strength, and over many years several pinnacles have failed, with consequential damage to the structure below the pinnacle. Fig. 1 shows a small tower on the Palace where the four corner pinnacles have either failed or been removed. This problem...
