Accuracy of elastic bending moments for the design of r.c.
floorslabs calculated with finite-element-software
Abstract: Design moments of conventional floorslabs are more and more analysed with finite element
programs. To get moments of sufficient accuracy for the design in practice, some principles are to
consider concerning the finite element mesh-layout, especially in areas of strongly increasing
moments. The influence of element size as well as square or distorted quadrilateral shape on the
accuracy of the calculated moments in r.c. floorslabs is evaluated by two typical examples, using the
finite-element-programs CS-FEBA  and MicroFe  The moments analysed by the finite element
method are compared to linear elastic solutions, given in tables [ l ] and [ 21.
