Pipe and Pipe Rack Interaction
Akbar Shahiditabar, Seyed Rasoul Mirghaderi

In current method of pipe and pipe rack design, first pipe is designed, and then pipe supports reactions are imposed on pipe rack. After that, pipe rack is designed according to the addressed loading. There are some ambiguities and problems in this pipe and pipe rack design method due to not modeling pipe in pipe rack design. The experienced damages in previous earthquakes confirm the mentioned claim. This study aims to propose a new method for considering pipe and pipe rack interaction instead of current method in order to solve current problems. In the proposed method, pipe is framed to pipe rack in all points and then pipe and supporting structure are design simultaneously. The proposed method is assessed by modeling in Sap and Caesar programs with nonlinear static analysis which results confirm our claims. In our suggested method, current problems are solved and the amount of used materials is reduced up to 29%.
