SEISMIC DESIGN OF PRECAST CONCRETE HOUSE

One of the most costly natural disasters to strike Indonesia is earthquake. Rebuilding after disasters, all too often has involved restoring the same structures (especially houses) that were inadequate to handle the threats imposed on them. Precast concrete offers a solution to this problem, because of the advantages of high quality factory made units, speed construction, and the reduction of site formwork and labor. Precast concrete offers a solution to this problem. The aim of this research is to investigate and design the precast concrete house for high (WG 6 and medium risk seismic (WG 4 zone by using SAP2000 v9 and nonlinear program LUSAS v13.5-7. The house is designed with open frame and infill frame structural system. Structural stability is the most crucial issue in precast design because it involves the precast components. The results of this research have the same dimension and rebar of each component for the same type of house and structural system. But, it is different for spread foundation. They have variation dimension in open frame and infill frame structural system, also in different seismic zone. It has been carried out on behaviour of connections, bearing capacity, column foundation joints, wall joints and their effect on the stability of the whole structure.
