Dynamic Deformation Capacity of Reinforced Concrete. Phase 5: Influence of Lacing Reinforcement

摘要

On behalf of MOD-NL/DWOO/HWO-CO blast tests were performed on simply supported reinforced concrete slabs. The resistance-deformation curves of the slabs were determined. From these curves, the deformation capacity of the slabs has been read. It was observed that the diameter of the longitudinal reinforcement has a considerable influence on the deformation capacity of the slabs and that it can change the failure mode. Concerning lacing, it was observed that it can only improve the deformation capacity if without it the slab would have failed due to buckling of the compression reinforcement. Two empirical relationships are found with which the deformation capacity of reinforced concrete slabs can be predicted. One is valid for failure in the compression zone, the other for failure in the tension zone.
