BEHAVIOUR OF REINFORCED CONCRETE FRAMED STRUCTURE SUBJECTED TO BLAST LOADING

The problem identified by research is the effects of blast loading on reinforced concrete structure. A comprehensive parametric study was conducted on reinforced concrete structure using the 3-D element model. In the analysis and design of structures are subjected to blast loads require a detailed understanding of blast phenomena and the dynamic response of various structural elements. This gives a inclusive overview of the effects of explosion on structures. Here in this paper, we are dealing with the blast force and its impact on the reinforced structure. The blast pressures i.e. reflected blast pressure, overpressure has been evaluated. From this value blast force has been evaluated. The values coming after displacement shows that as the floor height increases, displacement decreases. The result shows the bending moment, shear force, axial force. Displacement, axial force values of blast forces for charge 1500 kg at standoff distance 30m is greater. Hence it has been concluded.
