The analysis of concreting process impacts on the behaviour of residual liners of cast-in-situ voided slabs

This article reviews stresses caused by technological processes of concreting making an impact on void liners in reinforced concrete structures, and discusses the principles of void design. Through the application of numerical modelling, the paper considers the stress–strain status of the liners forming plastic residual voids under the loads acting in the floor slab. The authors provide a design solution to the liners forming voids.
