Parametric Study for Wind Design of Vertical Pressure Vessel as per Indian Standard
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
Like all other tall structures, determination of wind loads is important for industrial Pressure Vessel. All countries use different wind load standards. These different wind load standards are compared with each other in some studies. This paper describes a parametric study of wind load calculations on Vertical Pressure Vessel as per Indian Standard IS-875 (Part 4) (Ammendum 3rd 2006) with their latest addendums. The wind loads calculated, are applied to the design of structures to prevent failure due to wind. Calculated wind pressures as per different code on a Pressure Vessel produce actual loads on the structure. A good structural system for wind design is typically a strong, heavy system with robust connections to help resist loads as the wind blows across and over the structure. The Vertical Pressure Vessel is assumed to be made up of 3 components; First bottom dish which is supported on skirt, second intermediate Shell and Third top dish .The Vertical Pressure Vessel is 6.25 m tall and assumed which is locatedin urban terrain. The design wind speeds acting on vessel are to be calculated from corresponding codes. The wind force are calculated on each component as per Code procedure and checked for variation occurred. The factors like Basic Wind Speed, Terrain Category, Exposure Category, Damping factor are changed during calculation, the variation on wind force is plotted on graph.
