Integrated Analytical Procedure for Concrete Slabs under Impact Loads
Publication: Journal of Structural Engineering
Volume 120, Issue 6
Abstract
A multimass model is applied to simulate the impact‐load characteristics for an impact collision. Comparisons with verification tests indicate that the model is capable of predicting the resultant impact‐load characteristics and acceleration response. The multimass model is then linked to a dynamic finite‐element analysis for concrete‐slab structures through an interactive procedure. The interactive procedure is useful as the effects of effective mass and effective stiffness can be simulated accurately and upgraded at each time step. Finally, the ultimate behaviors and failure modes for reinforced‐concrete guardrails and fiber‐reinforced‐plastic (FRP) reinforced‐concrete slabs under impact collisions are studied. The kinetic energy transmitted by an impacting body as well as the energy absorbed by the concrete‐slab structures are found to be affected by the final failure modes in the structure.
