OBJECTIVES:

 To study the concept of buckling and analysis of structural elements.28

UNIT I BUCKLING OF COLUMNS 

States of equilibrium – Classification of buckling problems – concept of equilibrium, energy, imperfection and vibration approaches to stability analysis – Eigen value problem. Governing equation for columns – Analysis for various boundary conditions – using Equilibrium, Energy methods. Approximate methods – Rayleigh Ritz, Galerkins approach – Numerical Techniques – Finite difference method – Effect of shear on buckling.

UNIT II BUCKLING OF BEAM-COLUMNS AND FRAMES 

Theory of beam column – Stability analysis of beam column with single and several concentrated loads, distributed load and end couples Analysis of rigid jointed frames with and without sway – Use of stability function to determine the critical load.

UNIT III TORSIONAL AND LATERAL BUCKLING 

Torsional buckling – Combined Torsional and flexural buckling – Local buckling. Buckling of Open Sections. Numerical solutions. Lateral buckling of beams, pure bending of simply supported and cantilever beams.

UNIT IV BUCKLING OF PLATES 

Governing differential equation – Buckling of thin plates, various edge conditions -Analysis by equilibrium and energy approach – Finite difference method.

UNIT V INELASTIC BUCKLING 

Double modulus theory – Tangent modulus theory – Shanley’s model – Eccentrically loaded inelastic column. Inelastic buckling of plates – Post buckling behaviour of plates.
