Due to destructive earthquake seldom happen in Malaysia, Malaysian have lack of awareness and knowledge towards earthquake disaster. Hence, most of the buildings constructed in Malaysia do not consider lateral loads in the building design. This includes traditional houses in Lahad Datu that located in Sabah state of East Malaysia where moderate earthquakes had occurred in past decades. These houses may be vulnerable towards earthquake due to lack of appropriate lateral resisting system in place. In this paper, the seismic hazard in Sabah is first reviewed. It is followed by an experimental study on a 1/4 scale model of a traditional house. The building is a hybrid structure with the combination of timber main frame and small portion of concrete beam and slab which is a common construction in local community. The model was constructed and tested on uni-directional shake table using the ground motion recorded at KKM seismic station and scaled to 80gal. Seven Linear Variable Differential Transducers (LVDTs) and nine accelerometers were installed to record displacements and accelerations of the model, respectively. The displacements and accelerations at various parts of the model were analyzed and discussed.
