Analysis on Seismic Performance of Prefabricated Building Box Formwork Combination

Abstract

: The outbreak of novel coronavirus pneumonia since the end of 2019 has posed a great challenge to the world's public health security. According to the statistics of COVID-19 epidemic released by the World Health Organization, the global epidemic has accumulated more than 500 million infections and more than 6.2 million deaths. However, if all hospitals at all levels are changed to designated hospitals, it may cause a run on medical resources. Container building has the advantages of simple construction, short construction period, recyclability and cost saving, and can be effectively used in the rapid transformation of talent apartment buildings and general wards into designated hospitals for efficient use. During the COVID-19, Wuhan Huoshen Mountain Hospital and Leishen Mountain Hospital adopted the container structure design, which is similar to Lego, combining containers one by one, giving full play to the advantages of container buildings. However, the current container building code stipulates that container buildings are only applicable to low and multi-storey buildings with six floors or less. In order to improve the seismic performance of container buildings and expand the application scope of container buildings, this paper proposes a box form composite structure based on traditional containers. Through the analysis of mechanical performance parameters, it is concluded that the "strong column and weak beam
