000010489 520__ $$2eng$$aPressure vessels are one of the most important equipments in the refining of the crude oil. For this reason, these equipments must be resisting against the loads resulting from the earthquake. Pressure vessels are found in different units of refineries and in different vertical and horizontal shapes. These equipments are locating on different foundation and their seismic behaviors are quite different. For seismic study of pressure vessels, at first these equipments must be screened and categorized in order to find their real behavior. The selected sample should be a sample that in comparing to others must have critical condition in terms of seismic vulnerabilities. According to the qualitative studying, mechanical specifications such as dimensions, temperature, weight, and the dimensions of the foundation will be determined. After analytical modeling and calculations the amount of vessel vulnerabilities will be found. All the modeling is analyzed with the SAP2000 and SAFE2000 software. For modal and spectrum dynamic analysis shell elements and frame elements is used. After analysis is done, the stresses and the displacements in the body of vessel and also stresses in the pedestal and bolts will be determined and then compared to the allowable values. At the end those elements which have no adequate strength, will be retrofitted and all drawings and details will be presented.
