B2.4. Stiffened Plate
Problem Description
A two dimensional rectangular plate stiffened by a rectangular beam, subjected to vertical
loading is examined (Figure B2.3.1).

and stiffened by a rectangular beam of

width eccentrically placed with
respect to the centerline of the plate (Fig.B2.4.1) has been studied. The plate is clamped
along its small edges, while the other two edges are free.
Four cases are studied. According to the first one (Case1), a finite element solution is
employed using beam elements for the beam taking into account vertical eccentricity and
plate finite elements for the plate (results are obtained from ScadaPro and SAP2000
software). In the second case (Case2), a finite element solution is employed using plate
elements for the plate and shell elements for the beam (results are obtained from Nastran
software). In the third case (Case3), a finite element solution is employed using solid
elements for both the beam and the plate (results are obtained from Nastran software).
Finally, according to the fourth case (Case4), a boundary element solution (BEM) is
employed using boundary elements for both, the beam and the plate, and using the structural
model presented by Sapountzakis and Mokos in [18]. In Fig.B2.4.2 the structural models for
all four cases are presented.
