Abstract

Most of the Malaysian timbers have excellent mechanical strength properties which are suitably used as the main building structure components. Some of the Malaysian timbers achieve greater strength to weight ratio than both steel and concrete. Conventionally, structural use of Malaysian timbers is limited to roof construction only. To popularize the structural use of Malaysian timbers, timber-lightweight concrete composite (TLCC) system could be used as the industrialized building system (IBS) in local building construction. Shear connector is used in the timber concrete composite structure to resist the horizontal shear force and prevent slipping between interface of timber and concrete. This research focuses on the experimental study on structural behaviour of TLCC shear connectors. A total of twelve Kempas timber-foamed concrete composite specimens consist of six types of shear connectors were tested for push-out test. S1 and S4 without nail were used as the control specimens. S2 and S5, and S3 and S6 are provided with single and double nails respectively. The push-out test results indicate that connectors with double nails achieved the highest shear capacity followed by the single nail connector while plain connectors achieved lowest shear capacity. The connectors with nails showed good ductility and achieved the higher shear capacity and stiffness compared with the control specimens.
