Slender Composite Beam‐Columns
Journal of Structural Engineering, 1988A method for performing inelastic stability analysis of composite beam‐columns under different load and end conditions is presented. Nondimensional expressions describing the moment‐thrustcurvature relations are derived and then used to formulate and solve the governing differential equations.

Buckling of cracked composite columns
International Journal of Solids and Structures, 1990Abstract A crack in a structural element introduces a significant local flexibility which enhances the instability. Buckling of an edge-notched beam is studied for isotropic and anisotropic composites. The local compliance due to the presence of cracks in an anisotropic medium is formulated as a function of the crack-tip stress intensity factors and ...

Ductility of encased composite columns
This paper presents results ofanumerical study onreinforced concrete and fully encased composite columns designed according to the “Inerd” concept aiming at obviating the soft storey mechanism in frames subjected to earthquake. The model uses fibre beam elements with mono-axial non linear material laws for concrete, steel and reinforcing steel.Degée, Hervé +2 more

Tests on slender composite columns
Journal of Constructional Steel Research, 1999Abstract This paper describes two series of load tests on slender composite columns: eight tests on concrete filled rectangular hollow steel section columns and seven tests on concrete encased rolled steel joist columns, both with end eccentricities producing moments other than single curvature bending. In all tests, normal strength concrete of grade
