ABSTRACT
The prevention and control of the new coronavirus pneumonia outbreak poses an unprecedented and urgent need and challenge to the construction industry. The development of on-site rapid assembly steel buildings for epidemic prevention and disaster relief that can promptly resolve post-disaster risks and enhance the safety and security of people's lives is the inevitable choice, or even its only choice, in the event of a public health emergency. The development and application of assembled buildings is of strategic importance to enhance China's independent innovation and core competitiveness in the construction industry and to achieve sustainable economic and social development in the future. This paper analyzes the application and development of assembled buildings under public health emergencies by combing the history of the development of assembled buildings, combined with the current market situation research, to provide some reference for the practical application of assembled buildings under emergency events.
