I have experienced very heavy loads at the end of a buried piping connected to a concrete wall/tank in the order of 100 Tonnes. This is the Load case where piping is installed in summer 45 deg C and the operating temperature is 11 deg C in winter.

I have seen a proposal in an earlier post to sleeve this type of piping. The pipe is GRP and the diameter is 2500mm. We have tried few expansion loops. They do not seem to reduce the loads effectively. In order to reduce the load at the concrete wall, there is also a proposal to Rubber sleeve the piping as well. A 40 mm thick (2 m long) rubber sleeve is already in our standards just behind the concrete wall section. The prposal is to extend this by another 10 meters towards a 90 degres bend and again follow up to another 5 to 10 meters towards another bend. The rubber sleeve is coverd with gravel & compacted sand. Our idea is to get the expansion taking place against the direction of the wall. Can this be modeleled in Caesar in the Soil modeller.

Are there other practical solutions.

I appreciate Caesar experts and stres analysts giving some ideasa on this matter.

Thanks and regards
