Abstract EN
The dynamic large deflection response of RC beams under low-speed impact loading at their midspan is investigated in this paper.
Two simple methods such as extended Hamilton’s principle and equivalent static hypothesis are used to establish the theoretical models for both simply supported and fully clamped RC beams; analytical formulas for the maximum midspan deflection-input impact energy are obtained.
The “equal area” method based on the deflection history of beams is only used during these derivations to determine the plastic bending moment and the stress distribution of the structure.
Then, finite element simulations are carried out to verify the validity of the proposed predictions.
It is shown that the maximum deflections for both simply supported and fully clamped beams are almost proportional with respect to the input impact energy, which agrees well with both simulations and other experimental results.
Also, the boundary condition has more effect on the deflection response of the RC beams which is relatively longer.
