Calculation of Reinforced Concrete Floor Elements for Special Dynamic Loads under Technogenic Impacts

Abstract

The problem of calculating reinforced concrete structures for explosive and shock loads is considered. A method for evaluating beam structures when considering work in elastic, plastic is proposed. For the dynamic calculation of reinforced concrete structures for explosive and shock loads, the methods has been used in which dependencies are given to determine the parameters of dynamic loads arising from the explosions of various substances. The design scheme of the slab is represented as joint areas without cracks.The method of the dynamic method for calculating reinforced concrete slabs is presented, it allows to ensure the protection of the floor slab against collapse under the action of a special dynamic load. The plate deformation is considered in two stages of deformation: elastic, plastic.The proposed method for determining the safety of reinforced concrete slabs, while meeting the requirement of preserving the carrying capacity.A method in which the end of the elastic stage is represented through the ultimate elastic deflection has been used.Examples of calculation of the plate for the action of special dynamic loads are given.
