INELASTIC BUCKLING ANALYSES OF BEAMS, COLUMNS AND PLATES USING THE SPLINE FINITE STRIP METHOD

Inelastic buckling of thin walled structural members and plates is studied using the spline finite strip method. The analysis takes into account the non linear material stress strain properties, strain hardening and residual stresses. The plastic theories studied are the flow theory of plasticity and the deformation theory of plasticity. The spline finite strip method of inelastic buckling analysis is applied to a variety of instability problems including plates, cold formed columns, hot rolled columns and welded tee section beams. The buckling modes and loads computed are compared with theoretical values and test results (Author/TRRL).
