CE8402 – SYLLABUS

UNIT I ENERGY PRINCIPLES

Strain energy and strain energy density — strain energy due to axial load (gradual, sudden and impact loadings) , shear, flexure and torsion — Castigliano?s theorems — Maxwell?s reciprocal theorem — Principle of virtual work — unit load method — Application of energy theorems for computing deflections in determinate beams , plane frames and plane trusses — lack of fit and temperature effects — Williot Mohr?s Diagram.

UNIT II INDETERMINATE BEAMS

Concept of Analysis — Propped cantilever and fixed beams — fixed end moments and reactions — sinking and rotation of supports — Theorem of three moments — analysis of continuous beams — shear force and bending moment diagrams.

UNIT III COLUMNS AND CYLINDERS

Euler?s column theory — critical load for prismatic columns with different end conditions — Effective length — limitations — Rankine-Gordon formula — Eccentrically loaded columns — middle third rule — core of a section — Thin cylindrical and spherical shells — stresses and change in dimensions -Thick cylinders — Compound cylinders — shrinking on stresses.
