Test Study on Support Span of Sheet Sandwich Structure of Steel Fiber Concrete

Abstract:

The layer structure is a common structural form in the civil air defence. According to the shortage of the structure, a new type of structural form called steel fiber sheet sandwich structure is setup. For studying the influence caused by the support span of this structural form on structural blast-resistant ability, this paper has carried out a group of explosion model tests, which studies the optimal support span of this structure form and the influence on the failure characteristics of structure induced by the change of the support span. The test results show that: the support span of the steel fiber sheet is a very important factor for improving the whole structural blast-resistant ability; the thickness and support span of Steel fiber sheet shall make the steel fiber sheet not to reach the roof surface under the loads of explosion; the whole resistance of sheet sandwich structure in the tests is obviously higher than that of ordinary layer structure.
