Abstract:

The bending behavior of the simplysupported composite slim beam with deep deck and the stress and strain distributions in sections were investigated by test and FEM numerical simulation using software ANSYS.The results indicated that the sections of the beam remain flat during the elastic deformation stage, so the classical beam theory in material mechanics was used to analyze the bending stiffness of beam sections and the average stiffness of the simplysupported beam in combination with the measuring data in tests. A formula to calculate the bending stiffness of the simplysupported composite slim beam with deep deck was proposed.

Key words: civil architectural structure, composite slim beam, theoretical analysis, finite element method(FEM), bending stiffness
