Deflection Time History Fig. 18 shows the experiment's mid-span deflection time history, and the calibrated FE model in addition to the SDOF calculation, up to the peak response. The FE model curve has good agreement with the experimental result. The peak values of deflection obtained from the analysis and experiment are shown in Tab. 8. According to the findings, the FE model predicts the deflection response better than the SDOF calculation.
