In Taiwan, the building of steel structural presents a new trend of development after the earthquake on Sep. 21, 1999 that emphasize earthquake resistant properties. Steel structures have been used in high-rise buildings for nearly nine decades. Although are now adopted in generally building, steel companies lack a grading-based management system, resulting in a wide variation in quality among construction firms. Construction of low-rise steel residential structural buildings is normally under contract by low-level Iron Works. On the other hand, such structures without perfect inspection, often leading to defective in construction. The high failure ratio leads to potential hazards. For instance, the method adopted in America often leads to failure in the welding of beams and pillars together. However, the cost is higher than that of reinforced concrete buildings.
This study addresses issues involving safety and cost by modularity. Cases of low-rise residential building are studied, followed by analysis of the dimensions of the height from floor to floor and span of structure, as well as involvement of the facility size and construction practices. We also recommend standardizing steel components by mass production. Results of this study can contribute to efforts to reduce building costs and ensure that certified steel structural companies produce steel components according to strictly Japanese building code methods. In addition to identifying other appropriate materials, this study aims to achieve quality and cost control targets, thus making steel structures more reliable and competitive.
Key words: steel structure, modularity, safety, cost, quality
