Behaviour of RCC Structure Subjected to Blast Loading

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