Defining the damage and deflection from impact by using only energy could be misleading due to effect of momentum. In addition, reinforced concrete columns might subjected repeated loading. Hence, this study presents numerical simulation 16 RC with identical sizing reinforcement details, equal energy-double loadings a free-falling mass at midspan. The was kept constant for both impacts. For eac...

A structure, during its life, may be subjected to multiple hazards. These hazards are sometimes combined over a short period of time, or in some cases occur many years apart, with the first hazard influencing structural response under second hazard. reinforced concrete (RC) structure previously damaged by fire and then exposed seismic loading is one such example. To assess structures, effects o...
