Evaluation of Types of Shapes of Building Roof against Explosion

Abstract

Identification of danger of probable damage plays an important role in preparation for encounter and resisting negative effects of terrorist attacks to urban areas. The goal of pathology is identifying facilities and solutions of immunizing buildings against terrorist attacks and resisting explosion effects. with regard to this matter that the resistance of a building against blast wave depends on the shape and form of the building and the roof, the number of gates and opening power and genus of the material been used, therefore the study and assessment of types of shapes of building roof against consequences from explosion become important. So this research is going to compare different types of shapes of buildings roof against explosion waves. In this research in order to assess types of buildings roof, first by the use of resources from libraries types of buildings roof identified then in order to assess roofs in addition to finite element modeling, ideas of experts had been received. Next the consequences from those two procedures had been compared and types of roofs had been ranked based on the decline of explosion effect. And finally it had been concluded that three factors are effective in selecting the proper form, first the reduction of the area of the sectional area of the roof by increasing the height, the area of the roofs picture on the vertical plate, and being aerodynamic nature of the building roof.
