In Japan, old RC bridge-deck slabs were economically designed by small thickness without considering the fatigue resistance. These slabs are subjected to a huge repetition of moving loads. Therefore, they are suffering from fatigue damage. This damage is more significantly observed than that of slabs reinforced with deformed bars. To extend their fatigue life, a suitable strengthening technique is required ... إقراء المزيد

The safety of construction in the long-term performance is the main goal of structural designers. An example is seen in reinforced concrete (RC) bridge deck slabs that have been subjected to a large number of load repetitions. Therefore, many numerical and experimental studies have been conducted to predict the fatigue life of these slabs. Most of these studies focused on ... إقراء المزيد

There are many existing RC bridge slabs reinforced with plain bars, and they are suffering from a huge number of load repetitions due to heavy traffic. Therefore, a suitable strengthening technique is required to extend their fatigue life such as externally FRP sheets. To take full advantage of this strengthening technique, it is beneficial to use a numerical method to ... إقراء المزيد

An experimental study of shear behaviour of high strength reinforcedconcrete corbels with and without fibers was investigated. Seventeen high strength reinforced-concrete corbels were tested. The test variables were steel fiber content (Vf%), shear span-to-depth ratio (a/d), concrete strength (fcu), area of main steel reinforcement (Asm) and presence of horizontal stirrups. Test results showed that, addition of steel fibers or/and horizontal ... إقراء المزيد
