Abstract
Pressure vessels are widely used in private sectors and industries all over the world. Its safety and quality is major issues to avoid the failure of the system. In this paper response spectrum analysis of pressure vessel with vertical orientation is carried out. Vertical orientation pressure vessel is 6m in height and support height is above 1m. To understand the dynamic behaviour of the pressure vessel in actual conditions response spectrum analysis is performed in mastering software ANSYS 15.0. Manual calculation is carried out for seismic evaluation based on Indian Standards Codes IS: 1893 to validate the results.
