摘要：
The method is proposed for calculation of crack opening width in non-pressure reinforced-concrete pipes. The method is based on 3D finite element model. The calculation model of a pipe is developed as an array consisting of volume and bar finite element, simulating the concrete and the reinforcement respectively. Iteration method is used for calculations, and the concrete and steel deformation diagrams are applied. Cracking is taken into consideration by exclusion of concrete element chains in which the deformation reaches the concrete ultimate tensibility.
