Abstract: In order to increase the computational efficiency of pipes conveying fluid system with fibre reinforced polymer (FRP) layer under seismic and thermal loads, the ability of response surface (RSM) and kriging models is investigated. The two models of RSM and kriging are calibrated based on the analytical data points of maximum dynamical displacements, which are obtained by analytical analysis. Three input variables as thickness-to-radius ratio (h/R), temperature and the number of FRP layers are used to build the nonlinear models. The results show that the kriging model provides more accurate predictions compared to RMS. It is also found in the parametric study that the predictions by the kriging model closely follow the analytical results. By increasing h/R and FRP layers and decreasing temperature, it is found that the maximum displacements under seismic load of pipes are increased.
