ÖNORM B 5012

The purpose of this ÖNORM is to provide guidance for the structural analysis of buried pipelines. The calculation is based on generally accepted technical and field-proven principles. This ÖNORM contains a calculation method for buried pipelines and determines the stresses of piping systems made of all materials to be used for the transport of water / wastewater in pressure or gravity pipelines. The standard describes the design and structural analysis of buried pipes for all applications in water supply and sanitation on the basis of the calculation of stress, strain and deflection. There are established guidelines for the critical design criteria (stress, deformation and / or deflection calculation). The method is applied for all nominal diameters of pipes. However, for very large diameters the design in the installation of pipes may require the inclusion of other additional parameters, such as the homogeneity of the surrounding soil.
