Abstract: The structural design of pipe rack is a major component in the structural design of petrochemical construction. 3D collaborative design, which has advantages of visualization, real-time collaboration and high efficiency, is a developing trend in petrochemical industry. This paper tries to design the pipe rack using 3D software including PDS, SP3D and calculation software STAAD PRO, and discusses in detail the use of the software and the process of calculation, so as to give inspiration to structural engineers to improve the design efficiency and accuracy and promote the wider application of 3D Collaborative Design in the structural design of pipe rack.

Key words: design of pipe rack, 3D Collaboration, 3D software, calculation software, structural design
