Figures 6 and 7 show the comparison between the first six flexural mode shapes of ANSYS and FBEM models of SCCTB-1 and SCCTB-2.
Based on the developed SCCTB element, this study has also developed a FBEM program which can calculate the natural vibration frequency of SCCTBs that are common in the engineering practice.
(1) The FBEM's calculation results of the natural vibration frequencies of several SCCTBs agree well with the results of ANSYS's finite element calculations.
