OPTIMIZED DESIGN AND ANALYSIS OF STEEL PIPE RACKS FOR OIL AND GAS INDUSTRIES AS PER INTERNATIONAL CODES AND STANDARDS

Abstract

Optimized Design of Steel Pipe rack supporting structures in an Oil & Gas Industry is complex as one of the most important parts of structural systems for safe and stable production processes have been studied in this paper. In this thesis we have tried to design the Steel Pipe rack as per International standards which has been accepted most part of the world. Transverse direction is considered as Moment frame and Longitudinal as Shear connection to tackle the loading as per piping stress analysis. Plan bracing is provided in top and bottom tier so that lateral deflection can be optimized and distributed to the Anchor bay location. Anchor bay is provided in every Steel structure at maximum interval of. Vertical bracing is provided up to top tier on both Transverse and longitudinal direction so that all the lateral forces get transferred through this vertical bracing to the base. Fireproofing criteria has been also considered as per International standard to tackle fire hazard. The Structure has been designed in two parts as Strength design and Serviceability design for proper analysis and design of structure. Base Plate and Pedestal has been designed as per AISC codes considering support reactions. Then the Footing is designed in Staad Foundation by importing Staad model to get optimized footing design.
