ABSTRACT

The German Worksheet ATV-M 127-2 published in January 2000 after a seven years period of preparation and discussion is now well accepted in design practice for lining systems made of different materials and installed in various methods. The concept based on stress, deformation and stability analyses supports simple formula and diagram usage in standard cases like circular pipes up to ND 600 and more elaborate analyses for non-circular cross sections. Beside a short description of the design code the theoretical background is presented. Experimental test configurations are discussed regarding restrictions such as test specimen length, friction and load distribution. There is need of further research projects in co-operation with other universities to solve the problems left in theory and in practical use.
