Zum Kriechen von Sandwichelementen unter axialer Belastung.

Creep of axially loaded sandwich panels In the design of sandwich panels subjected to compressive axial loads (apart from uniformly distributed loads vertical to the plane of the panel and temperature difference) effects according to 2nd order theory must be taken into account. Deflections are determined considering shear deformation of the core material which is highly influenced by creep effects. For pure bending the wide variation of creep coefficients depending on the composition of the core material is considered by sandwich panel producers by declaring creep coefficients for different load time periods. The question is how these coefficients may also be used for the design of axially loaded panels taking into account deformation due to creeping. For this purpose axial creep tests were performed at iS‐mainz. Based on the results of both this research and the FP7‐project EASIE coordinated by iS‐mainz a design procedure for axial loaded sandwich panels is proposed which will also be contained in the draft of prEN 1993‐7 Design of steel structures – sandwich panels.
