Structural Behavior of Two-Way Slabs Reinforced with Low-Ductility WWF
Concrete slabs usually have small flexural reinforcement ratios and are considered to be very ductile structural members. However, this is not true for slabs containing low-ductility tensile reinforcement. These slabs fail in a brittle manner by rupture of the reinforcement at relatively small deformations. This is because many of the assumptions implicit in the design of flexural reinforced concrete members are not applicable for such structures. Concrete slabs that are reinforced with low-ductility steel welded wire fabric (WWF) are not able to absorb energy generated by the applied loads and lack robustness. This paper presents the results of laboratory tests on 11 two-way square and rectangular corner-supported reinforced concrete slab panels containing either low-ductility WWF or deformed bars with normal ductility. The slabs were subjected to deformation controlled transverse loads applied by an actuator. The results of the tests are presented and evaluated with specific focus on the ductility, mode of failure, and strength of the slabs.
