Paper Details

Currently in any plant, manufacturing shop, assembly shop, maintenance shop etc. has variety of structures,sysytem and equipment comprising of primary civil structure, secondary supporting structure, supporting systems andequipment viz. tanks, vessels, heat exchangers, piping, supports, valves, pumpls, fans, blowers, motors, compressors,diesel generator etc. Seismic Analysis of any plant structural is the calculation of the response of structure ofearthquakes. It is the part of the process of structural assessment and retrofit in regions where earthquakes aredominant. There are generally two methods for seismic qualification of various systems. First method is the qualificationby testing, in which qualification is performed by shake tabel testing, however shake table testing is not feasible for thesystems with excessive weight and large size. Second method is the qualification by analytical methods, in whichanalytical models are required for developing assembly/component. FEA model is developed and checked under staticcondition after applying sufficient bondary conditions and loading in this method. Modal analysis is done to find thenatural fequency of the sysytem. On the basis of this, harmonic and transient analysis carried out and visualizing theresponse of sytem under given condition in form of stress, deformation etc.
