An evaluation of structural joint in IBS construction

Abstract

Precast concrete slab and shear wall are leading the Malaysian construction industry as the usage of the precast component has increase from previous years. This thesis of evaluation of joint structure in Industrialized Building System (IBS) is to determine what type of joint structure implemented in Sungai Chuchuh residential college. In order to determine the type of joint two model of precast slab are develop using Staad Pro 2004. The first model consists of shear wall and precast slab constructed with dowel bar and the second model is constructed without the dowel bar. Construction drawing is taken to develop these two models as to ensure the dimension is exact with construction site. Next, the combination loading of dead load and live load are assigned to the models structure to produce an accurate output for the whole residential college. The objectives of this study are to determine the moment capacity, shear forces and the displacement form the two models. Based on the output produce by the Staad Pro 2004 evaluation can be made from the bending moment, shear force and the displacement diagram. In additional, the types of joints are pinned, semi rigid and rigid joint connection. These three connections is differ in term of the strength, ductility, cost, and advantages. Next, after comparing the result output with the diagrams form another study attached on the literature review a conclusion can be made that the type of joint connection for the IBS structure at residential college of Sungai Chuchuh is a rigid connection.
