Abstract

Precast concrete half slab system, which consists of precast concrete at the bottom part and cast-in-site concrete at the overtopping, is widely used as floor slab and commonly behave as a one-way slab. However, the problems occur when the precast half slab is designed as the two-way slab system. In this system, the connection of between precast concrete slabs should able to handle the two-way moment of the whole panel, without causing any significant damages. Hence, an innovative rigid connection between precast concrete slab components in two-way half slab system is presented in this paper. The objectives of this research are to conduct the experimental study for proposed connection between precast concrete slab components that behave as two-way half slab system. The 2200 mm × 2200 mm size of samples are performed using the triangular shape of the rigid connection between precast concrete slabs. The test is conducted using mid-span concentrated loading-unloading up to failure condition. The test results are observed and verified with the response of monolith reinforced concrete slab system using the same loading pattern. The verification results show that proposed half slab system are able to withstand the two-way moment loading. Although the carrying capacity is still slightly lower than the monolith reinforced concrete slab system, the proposed half slab system is able to apply as the structural component.
