WebOct 1, 2013 · 1. Introduction The Rayleigh–Ritz method is a variational method to solve the eigenvalue problem for el-liptic differential operators, that is, to compute their eigenvalues and the correspondingeigenfunctions. It is the direct counterpart of the Ritz method for the solution of the as-signed boundary value problems. WebA theoretical calculation method based on the Rayleigh-Ritz method was introduced, and the equations corresponding to the two failure modes were derived. Using this proposed model, both the failure mode and bearing capacity of the glulam beam string can be estimated accurately.
