RESEARCH ON THE ELEMENTAL RATIO OF PRECAST CONCRETE COMPONENTS AND ITS CONSTRUCTIBILITY IN THE REINFORCED CONCRETE HIGH-RISE HOUSING

Abstract

In industrialization of reinforced concrete construction, precast concrete components has contributed to up-grade constructibility among other methods like pre-assembly of steel reinforcement and systematization of forms. This paper deals with the typical floor of reinforced concrete high-rise housing in 9 precast components such as internal, external, and corner columns ; internal, external, and auxilliary beams ; floor slab ; balcony ; and external wall. It considered the influence of the use of industrialised building components in the ratio of steel bars, forms, and concrete used, and the aspect of constructibility. It clarifies the advanced use of non-structural components more than structural members and the reduction of form works over reduction in concrete works.
