Abstract :

The Structural Integrity Of Static Process Equipment Is Critically Influenced By Environmental Loads, Particularly Wind And Seismic Actions. This Paper Presents An Integrated, Code-compliant Methodology For Wind And Seismic Design And Analysis Of Two Representative Equipment Types — A Vertical Pressure Vessel And A Horizontal Fixed Tube Sheet Heat Exchanger — In Accordance With ASME BPVC Section VIII Division 1, IS-875 (wind Loading), And IS-1893 (seismic Loading). For The Pressure Vessel, A Natural Frequency Of 26.9856 Hz Confirmed Rigid Structure Classification. Wind Loading Governs Bending At The Critical Leg Section (120.607 Kg-m Vs. 45.125 Kg-m Seismic, Ratio 2.67:1). Wind Deflection Of 3.852 Mm Is Well Within The 10.500 Mm Allowable, And Critical Vortex-shedding Velocities (658–717 Km/hr) Confirm Zero Vibration Risk. For The Heat Exchanger, Wind Governs The Saddle Element (435.25 Kgf) While Seismic Governs Regular Shell Elements (25.64 Kgf/element). A Unified Governing Load Comparison, Code Compliance Summary, And Recommendations For Further Work Are Presented, Providing A Practical Framework For Engineers Performing Multi-hazard Static Equipment Design Under Indian Code Conditions.
