| چکیده | ||
| Concrete two-way slabs could be subjected to impulse load due to accidents, which force the structural member to undergo strain hardening faster than its ability to dampen and absorb much of the applied energy, which has not previously investigated in the literature. Theoretical and numerical models were developed and validated against experimental results to explore this behavior. A reinforced concrete square slab of 1 m length and 0.08m thickness was simulated with several case studies investigated, such as the impulse load intensity, concrete compressive strength magnitude, the model's free vibration, and the model solution. It was concluded that the slab's response under impulse load depends, to the first degree, on the impulse quantity. If this sudden load equals two-thirds of the static load, the model starts to show visible cracks. Furthermore, the maximum displacement does not necessarily occur at the instant of loading; unlike static conditions, the designer can expect the higher deflection several seconds after the applied load is applied. | ||
