The problem uses the BM3 piping system model from an actual nuclear power plant found in the Nuclear Regulatory Commission’s report.[1][2] The model consists of three anchors, three piping subsystem branches, and elastic supports:
To measure the influence of each effect and compare the response-component combination methods, seven single-point response spectrum (SPRS) analyses are performed.
The results of a full-transient (direct time-integration) analysis are used as a baseline.
