Abstract:
This article presents the basis of a procedure to predict the flexure impact resistance capacity of reinforced concrete (RC) members. A series of physical experiments were conducted to confirm the procedure applicability in predicting the flexure impact resistance capacity of RC members. Test results also show that the procedure was capable of correlating damage levels in RC members to loads resulting from collisions. The basis of the procedure relies on performing Monte Carlo statistical (MCS) simulations in conjunction with the displacement-based design (DBD) method. Results from the MCS simulations indicate that the measured peak and residual displacements from the physical experiments were predicted within a 95% confidence interval. This level of confidence suggests the validity of the analytical methods in estimating the flexure impact resistance capacity of RC members.
