PLASTIC DESIGN OF BEAMS WITH VARIABLE CROSS SECTIONS

Geometrically Nonlinear Theory of Composite Beams with Deformable Cross Sections

Aone-dimensional theory of slender structures with heterogeneous anisotropic material distribution is presented. It expands Cosserat’s description of beam kinematics by allowing deformation of the beam cross sections. For that purpose, a Ritz approximation is introduced on the cross-sectional displacement field, which defines additional elastic degrees of freedom (finite-sectionmodes) in the on...

On The Plastic Design Of Timber Beams With A Complex Cross-Section

For the design of steel and concrete structures, most modern international design codes allow the use of plastic stressstrain-diagrams for the analysis of the bending resistance of the cross-section in the ultimate limit state. Curiously, in Europe and most other parts of the world, timber structures are still designed for the ultimate limit state with the old, conservative concept of full elas...

Bending of Beams with Unsymmetrical Sections

Advanced Optimization Design of Cross Beams Structure

Solid Isotropic Microstructure with Penalization(SIMP) in topology optimization was deeply analyzed, and thus SIMP topology optimization criteria algorithm was deduced. Simulation analysis to the results was also conducted by Ansys, so as the structural lightweight design to machine crossbeams of the HTM series gantry. By verifying, the structure was 3.8% lower than the traditional structure qu...
