Simulation of Blast Load on a Reinforced Concrete Slab in the Time Domain

Abstract

The article aims at simulation and analyses of reinforced concrete slabs under blast load by finite element method in LS-DYNA. Properties of rebar and composite materials have been changing. The study of efficiency has been performed. The problem of estimation of bearing structures of buildings is extremely urgent due to the increasing incidence of domestic gas explosion in emergency actions, hitting vehicles on the construction of buildings and structures, man-made disasters, acts of terrorism. At present, when calculating the frame of a building for progressive collapse, the technique of removing the heaviest column of the first floor is applied. However, existing methods for calculation of buildings on the progressive collapse caused many disputes. The paper considers simulation of emergency response using the finite element method in the calculation of reinforced concrete frame elements of a building.
