Abstract
Public agencies are investing in the development of community shelters as resilient structures to provide a place of refuge for citizens during extreme wind events. An analysis of code based design parameters for traditional assembly type dome structures is contrasted with the an analysis of design parameters required by the United States Federal Emergency Management Agency (FEMA) document 361- “Design and Construction Guidance for Community Safe Rooms”. It demonstrates that the factors governing the code based design of thin shell domes are such that an extension of FEMA 361 compliance requires a marginal increase compared to alternate building types.
