Load acting on civil defence works from the collapse of the above structure
Abstract
Research on special load bearing structures has been carried out widely. Many countries have designated specific design standards for special constructions (civil defense works) [1,2]. The research in Vietnam has many limitations. Vietnam university research are mainly theoretical and result-updated. Experiments were only carried out in the Department of Defense with special Private clairvoyants that used real models. Determining the specific load from structural collapse is one of the research areas that have emerged since the terrorist attacks of the twin towers in the United States in 2001. Beside the high casualties and severe property damages by the immediate special forces on the frames, researchers also consider the effect of the destroyed structures on the basement. This paper presents the initial assumptions about determining the load from the above structural collapse which aims to secure the basements in the event of structural collapse due to the risk of wars and terrorism.
Keywords: Special loads; civil defense; overhead structure collapse.
