COMPARATIVE STUDY OF STRUCTURAL MATERIAL QUANTITIES OF MULTI-STOREY LINEAR-TYPE RESIDENTIAL BUILDINGS

摘要

One of the main factors in the selection of the structural system for a multi-storey linear-type residential building is the initial construction cost of various structural systems. In many Asian countries, composite steel and concrete construction, and cast-in-place concrete framing construction are the most commonly used structural systems. However, there is insufficient data related to relative construction costs of these two structure types. In this paper, a representative floor plan was developed based on the examination of existing buildings of this type. A comparison of structural material quantities for representative building models up to 40 storeys in height using both types of structural systems was performed. Six models were developed based on a typical floor plan and were designed for gravity and lateral loadings. Quantities of materials for each model were calculated and compared in terms of each main structural material such as steel, concrete and reinforcement, and ratios of structural material quantities. The information presented can be utilized with appropriate cost data to compare estimates of initial construction costs of the two structural systems.
