Comprehensive Economic Analysis of Low-rise Steel Residence in the South of Jiangsu Province

Abstract

The feasibility and advantage of steel structure applied to low-rise residences in the south of Jiangsu were analyzed firstly. In order to compare the comprehensive economic benefits between the steel structure residence and the traditional reinforced concrete residence, two-story houses with steel structure and reinforced concrete structure system were designed respectively on the basis of the certain foundation and load conditions in southern area of Jiangsu. The calculation and comparison of specific economic indicators show that the labor cost of low-rise steel structure residence is significantly lower than that of concrete residence while the material costs of low-rise steel residence are more. Generally, the total cost of steel structure is slightly more expensive than that of concrete structure. However, for the long-term comprehensive economic benefits, the application of steel structure in low-rise residences is not more disadvantageous compared with concrete structure. The research work has some reference value for popularization low-rise steel structural residences in the south of Jiangsu. 1 introduction Construction of small town in China has developed rapidly in recent years, then a large number of the residential building of the goods have been built. In long-span structure and high-rise structure, steel structure's basic theory and applications have had a more perfect result. In the field of multi-storey and high-rise residential areas, some successful experience in engineering have been accumulated. But in terms of the application and promotion, the study of steel structure mostly focuses on the city multi-storey and high-rise housing. Applied in the research and application of low-rise town residences are very little. The feasibility and comprehensive economic benefits of the application of steel structure in small residences in the south of Jiangsu are mainly discussed. In southern regions of Jiangsu, the economy is developed and the urbanization level is high, so it has the advantage of promoting small steel structure residential industrialization. 2 the feasibility of p romoting low-rise steel structure residential industrialization in the town of south Jiangsu
