An Influence of the Mesh Size on the Results of Finite Element Analysis of Z-Purlins Supported by Sandwich Panels

In this paper the questions of numerical analysis of thin-walled Z-purlins in the coverings of buildings made of sandwich panels are considered. Numerical analyses are done in the program MSC.NASTRAN. An influence of the mesh of elements on the results of calculations is studied. The results of carried out numerical analyses allowed developing the method for determining the stiffness of connection purlin with sandwich panels.
