The second-generation wavelet scale function shows the weakness of no expressions, the curve-fitting method is proposed. Bar-beam elements are constructed based on Daubechies wavelet and second- generation wavelet, wavelet function is used to construct interpolation function. The wavelet interpolation coefficient is transformed to physical space through the transformation matrix. Precision validation of the bar- beam elements constructed is conducted by numerical examples. The results show that the wavelet finite element has high precision in solving deformation and strain.
