Abstract—In this paper, desired data from the modal analysis will be obtained from ANSYS using tubing assembly structure model. The FRS data is obtained from the geographical region where this structure will be mounted. Those data will be used for performing response spectrum analysis, which is essential data for designing a structure. Therefore, it was possible to determine whether the structure is safe through. In my current project the scope of work includes, Creating 3d model of the tubing assembly structure. Modal analysis to study the fundamental frequencies of the structure Dynamic analysis: To evaluate seismic response of the system under Operation Basis Earthquake (OBE) and Safe Shutdown Earthquake (SSE). The response spectra used for SSE in X, Y, Z directions are given as input. Calculation of stresses in the beam elements as per ASME section, sub-section NF for the above load cases are done, also Verification of adequacy of welded/nut bolt joints are done. In this project “g” values at five locations where maximum accelerations occur are computed. Design optimization of the structure was done based on the results obtained.
