Design and Validation of Spherical Pressure Vessel under Seismic Loads using FEA as Per ASME

The present work involves design, modeling and analysis of spherical pressure vessel. In the design of pressure vessel safety is the essential thought, because of the potential effect of conceivable accident. High pressure rise is created in the pressure vessel and pressure vessel needs to withstand extreme forces. The generally applied loads are dead loads, live loads, snow loads, wind loads, seismic loads, thermal stresses, shock, e.g., by crane, fatigue loads, soil and water pressure and others, e.g., load from mechanical device. This work is focusing on designing a spherical pressure vessel as per ASME codes, geometric modeling using CATIA V5 R20 and FEA validation using ANSYS 14.5. Endeavors are made in this work to design the pressure vessel utilizing ASME codes & standards to authorize the design. The obtained FEM results are contrasted with analytical ones and a decent agreement between them is noticed. The seismic resistant design for these bigger storage tanks has turnout to be more critical in terms of safety and the environmental impact on society overall. This work is also focussing on seismic resistance design of a pressure vessel.
