Abstract:
|
This paper examines the impact responses of reinforced concrete RC beams through an experimental study and presents an
analytical model developed to predict the maximum midspan deflection and maximum impact load, which aids as an important performance
index to evaluate the damage levels of RC beams when subjected to impact loadings. The experimental study involves a drop
hammer impact test and investigates the influence of drop height and the effect of the amount of longitudinal steel reinforcement
contributes to the response of RC beams. The RC beam specimens used in the experiment comprised of under-reinforced sections
provided with sufficient amount of transverse reinforcements to allow for an overall flexural failure. The experimental impact responses
of the RC beams were simulated with two-degree-of-freedom mass-spring-damper system model, in which the loading rate effects were
duly considered. The analytical results are in good agreement with the experimental results for the RC beams that exhibited overall
flexural failure. |
