INFLATION FORMING OF STEEL FIBER-REINFORCED CONCRETE DOMES

摘要

Inflation forming steel fiber-reinforced concrete shell structures suitable for shelters and fortification is shown to be a viable construction method. The technique of construction is based on experience gained building a series of 9-foot diameter domes of variable thicknesses. The preliminary stress analysis for a 28-foot diameter dome of variable thickness using a finite element method shows that the steel-fiber concrete is not highly stressed for the loads and boundary conditions investigated. The buckling analysis was not completed in time to be included in this report: preliminary values are presented.
