Analysis of Shallow Buried Reinforced Concrete Box Structures Subjected to Air Blast Loads Introduction Program Flowchart A numerical method for the dynamic analysis of shallow-buried reinforced concrete box-type structures subjected to air blast has been developed. The method is based on the Single-Degree-of- Freedom (SDOF) approach and considered the effects of compression and tension membranes in reinforced concrete slabs, direct shear, soil arching, soil-structural interaction, and P-I behavior assessment. A rational model has been incorporated for varying SDOF equivalent load and mass factors for the dynamic analysis. Flexural Mode Resistance Function o Externally applied thrust due to vertical wave propagation in soil o Horizontal thrust at roof and floor varies with time o Slab compressive and tensile membrane action using strip method Pv(t) Validation with Experimental Data o Using results from Kiger and Getchell (1980), and Slawson Compressive steel εcu fsi (1984) Foam Hest te Less
