Design and optimization of the pipe fixed supports in the super high-rise building

The finite element (FE) technique is applied to conducting the strength design and optimization of the vertical pipe fixed supports in a super high-rise building. The FE model of the fixed support is created and the stress distributions are calculated by using ANSYS. In this paper a new method is given to install the fixed supports by multi-layers. Lug-supports are welded on the locations where large stress is high so that the stress can be decreased and the overall structure has certain strength. These methods can apply as instructions for the design of the pipe fixed supports of the vertical pipelings in super high-rise buildings.
