Constitutive properties of rectangular single-cell cross-section

Coefficient Units Value 1 Deviation [%] Value 1 Deviation [%]  

The curved cross-section is divided by a central web into two cells. The associated geometric description is given by Elqs. (10.10) and (10.11). On this basis, the radius of curvature R and generating half-angle C may be expressed in terms of the beam width b and the ratio no/f, between the extents along 

In Remarks 10.3 to 10.6, the wall properties around the circumferential contour have been specihed. For the central web, however, an altered configuration may be selected. In the beam property adaptation of Section 10.2.2 for 

The stiffening due to the assumption of a cross-section without strains, respectively curvatures, in its plane visible in the right-hand columns of Tables 10.5 and 10.6, has been found to be not very realistic. Hence, the subsequent calculations will be conducted by means of the assumption of a cross-section without loads in its plane. The results obtained for such a shell description of the beam walls are, furthermore, to be compared to the outcome of the significantly simpler membrane description. As briefly mentioned in the introduction to this section, three different solution approaches will be examined. The associated individual restrictions are discussed in the following.
