Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered in this paper. It is shown that web crushing strength depends on the level of applied deformations as well as the level of applied lateral and axial forces.

It is important that this waste, like any other waste, is disposed of safely and responsibly. Concrete can be crushed into aggregate and re-used elsewhere for building roads and as base materials for paths, patios, driveways, hard-standings, gabion baskets for retaining walls or terracing. On site concrete crushing for re-use
