چکیده
Abstract In order to study the damage law of cuboid explosives reinforced concrete beams under contact explosion, effect action different length-to-width ratios, explosive heights and equivalents is studied by LS-DYNA numerical simulation.The results show that when amount height remain unchanged, ratio length width 1:1, volume largest. When decreases with increase in height. length-width-height constant, increases linearly equivalent. The degree beam divided into three grades: Reinforced slightly damaged η <3%. moderately 3%< <7%. serious η>7%.

Damage Assessment of Reinforced Concrete Buildings Considering Irregularities (RESEARCH NOTE)
Structural damage can be controlled in performance based seismic design (PBSD) according to the requirement under a certain hazard level. During strong ground motion (GM) such buildings suffer minor to major damages depending on the shaking level of GM. The available damage assessment methods are complex, tedious and time-consuming procedure. In the present study, a simplified empirical model h...
متن کاملBehaviour of Reinforced Fibrous Concrete Beams under Reversed Cyclic Loading
When earthquakes occur, energy released by the earthquake gets induced into the structure as ground motion and this energy has to be dissipated for safety reasons. To release seismic energy, the structure should damage in such a way that on one hand, collapse of structure should not occur and on the other hand, after the earthquake, damage should be economically feasible to repair. To avoid the...
متن کاملNumerical Study on the Flexural Behaviour of Concrete Beams Reinforced by GFRP Bars
Enhancement of the response of reinforced concrete (RC) beams using fiber-reinforced polymer (FRP) reinforcement bars has become a popular structural technique over the past two decades due to the well-known advantages of FRP composites including their high strength-to-weight ratio and excellent corrosion resistance. Thisstudy presents n...
