this contribution presents the effect of a coarse warping descriptor on the first natural angular frequencies of a clamped-clamped thin-walled beam with non-symmetric cross-sections. By means of a direct one-dimensional model, leading to ordinary differential field equations, the linear dynamics of such a pattern scheme is investigated. The effect of warping and warping constraints is taken into account, and the results are compared with those of a numerical commercial code and of a recent set of laboratory experiments. The agreement is satisfactory; we describe the investigations completing this contribution, which are in due course.

Abstract
this contribution presents the effect of a coarse warping descriptor on the first natural angular frequencies of a clamped-clamped thin-walled beam with non-symmetric cross-sections. By means of a direct one-dimensional model, leading to ordinary differential field equations, the linear dynamics of such a pattern scheme is investigated. The effect of warping and warping constraints is taken into account, and the results are compared with those of a numerical commercial code and of a recent set of laboratory experiments. The agreement is satisfactory; we describe the investigations completing this contribution, which are in due course.File in questo prodotto:
