Abstract: Optimal cross-section design of beams plays a characteristic role which signifies the rigidity of
the member in bending, shear and torsion load conditions. Practically modern overhead crane girders,
railway bridge girders or rail tracks etc. require constant cross-section along the axial direction.
Conventional topological optimization modeling procedures in such cases prove inadequate for the reason
that these procedures generate non-uniform topologies along the axis of the bending member. To examine
optimal topology of those structural bending members monly possess constant cross-section
along the axis the topology optimization with extrusion const
