OBJECTIVE:

To learn the computation of deflection of beams and trusses using energy principles, analysis
of indeterminate beams and columns, state of stress in three dimensions.
UNIT I ENERGY PRINCIPLES 10
Strain energy and strain energy density – Strain energy in axial force - shear, flexure and
torsion – Castigliano’s and Engessor’s theorems – Principle of virtual work – Application of
energy theorems for computing deflections in beams, pin jointed frames – Maxwell’s
reciprocal theorem.
UNIT II INDETERMINATE BEAMS 9
Propped Cantilever and Fixed Beams – Fixed end moments reactions, slope and deflection
for standard cases of loading –– Continuous beams – support reactions and moments –
Theorem of three moments – Shear Force and Bending Moment Diagrams
UNIT III COLUMNS 8
Behaviour of short and long columns. Euler’s theory of long columns – Critical loads for
prismatic columns with different end conditions - Rankine-Gordon Formula - Eccentrically
loaded long columns -Eccentrically loaded short columns - middle third rule – core of section .
UNIT IV STATE OF STRESS IN THREE DIMENSIONS 8
Determination of principal stresses and principal planes – volumetric strain – Theories of
failure – Principal stress, principal strain, shear stress, strain energy and distortion energy
theories – Application in analysis of stress, load carrying capacity and design of members.
Interaction problems - interaction curves.
UNIT V ADVANCED TOPICS 10
Unsymmetrical bending of beams - symmetrical and unsymmetrical sections, shear centre –
stresses on curved beams for simple solid sections – Winkler Bach Formula – Thick cylinders
– Compound cylinders - Residual stresses – Stress concentration – Fatigue and fracture.
TOTAL: 45 PERIODS
