Study On Steel Structure Housing Industrialization Promotion In Jiangsu Province

Steel structure houses are favored because they have many advantages. For example, they are lighter and more anti-seismic, they can save time for construction; they are highly industrialized and environmentally friendly as well. With these remarkable advantages, SSH can keep pace with the requirements for a sustainable development of the national economy. Since the government encouraged the use of more steel structure, steel production has increased substantially. Steel structure used in construction has seen a rapid progress in recent years, especially in the field of housing construction. It is generally accepted that SSH will satisfy the development of our national economy, because in this kind of cost-saving houses, clay bricks will be replaced by cheaper mass-produced wall materials. In addition, a new efficient heating system will be involved. All these will make houses more comfortable, more functional, more automation-oriented, and more industrialized. SSH will be one of the major trends in the development of the housing industry for the 21st century.As the development of steel structure as well as the remarkable progress achieved in the research of this field, people became more concerned about the comprehensive evaluation of the architectural system of SSH as well as the industrialization of SSH. Especially, about the difference of the ratio of function to cost between SSH and houses with other structures and how to promote steel structure housing industrialization. In order to promote the steel structure housing industrialization in Jiangsu province, a research was conducted to comprehensively evaluate steel structure houses. It aims to identify the reasonable system for Jiangsu province, and provide a scientific support for investment decision-making in housing industry. It is hoped this research will be helpful to reduce wrong investment decisions in using steel structure and promote the healthy development of Chinese economy.The main tasks and conclusions of the dissertation are as follows:1)Identify the reasonable system for Jiangsu province by AHP, based on the experiences in some cases, a comprehensive and systematic analysis of steel structure houses buildings was given in view of technical and economic factor for medium high-rises and high-rises. And compare them with system of concrete structure and brick-concrete construction.2)The real cases which are calculated and analyzed are conducted about the structural and economic properties of SSH in medium high-rises and high-rises. And give a comprehensive evaluation of the architectural system3)In the process of evaluating the sustainable development of this construction system, a concept has been got involved, that is, circular economy. A comparison of the concept was given between SSH and concrete structure system. It will give some advice to the sustainable development in the construction field.
