Abstract

Abstract

In order to promote the application of wavelet theory in structural computation, Daubechies wavelet Galerkin method is studied to computate the structural fundamental components.Because the displacement curve solved by the present Daubechies wavelet Galerkin method is not continuous, computation of high precision is hard to conduct.combining with generalized variational principle and Lagrangian multiplier method, Daubechies wavelet Galerkin method could be modified to form Daubechies conditional wavelet Galerkin method to be employed in structural computation.Taking the structural fundamental componentsbar and beam for examples, the construction of Daubechies conditional wavelet Galerkin method is elaborated.And the new method is compared with common FEM and present Daubechies wavelet Galerkin method at the same time.Typical computation examples were used to verify the accuracy of Daubechies conditional wavelet Galerkin method．
