Behavior of Laminated-Timber Slab Using Mechanical Connector

Abstract

The behavior of the floor slab supports the function of the slab. In high-rise residential buildings, the behavior that needs to be known is due to the presence of static load and vibration load. Behavior due to static load is the flexural behavior of the floor slab due to the loads that work on it is the gravitational load. This study discussed the bending behavior of laminated timber floor slab due to static load. The scope of the research is the wood used is Mersawa wood (Anisoptera spp.), The test used three point loading test in accordance with ASTM D143, the behavior discussed is flexural strength, the laminate floor slab is arranged horizontally with the mechanical connector that is bolt with 10 mm diameter. The test shows that the average bending capacity (proportional limit load) is 25.65 kN. The failure mode occur is simple tension. The result of the test indicated that, in general the proportional limit load is higher than service load, so the floor slab can be used for residential building, such as multistory buildings. The deflection of wooden floor slabs due to static and vibration loads is smaller than the permit deflection limit. These results indicate that the slab has sufficient stiffness and has adequate comfort to the vibration.
