STRUCTURAL ANALYSIS – CLASSICAL METHODS
3 1 0 4
The members of a structure are subjected to internal forces like axial forces, shearing forces, bending and torsional
moments while transferring the loads acting on it. Structural analysis deals with analysing these internal forces in the
members of the structures. At the end of this course students will be conversant with classical method of analysis.
DEFLECTION OF DETERMINATE STRUCTURES
Principles of virtual work for deflections – Deflections of pin-jointed plane frames and rigid plane frames – Willot
diagram - Mohr’s correction
MOVING LOADS AND INFLUENCE LINES
(DETERMINATE & INDETERMINATE STRUCTURES)
Influence lines for reactions in statically determinate structures – influence lines for members forces in pin-jointed
frames – Influence lines for shear force and bending moment in beam sections – Calculation of critical stress resultants
due to concentrated and distributed moving loads.
Muller Breslau’s principle – Influence lines for continuous beams and single storey rigid frames – Indirect model
analysis for influence lines of indeterminate structures – Beggs deformeter
Arches as structural forms – Examples of arch structures – Types of arches – Analysis of three hinged, two hinged and
fixed arches, parabolic and circular arches – Settlement and temperature effects.
SLOPE DEFLECTION METHOD
Continuous beams and rigid frames (with and without sway) – Symmetry and antisymmetry – Simplification for hinged
end – Support displacements.
MOMENT DISTRIBUTION METHOD
Distribution and carry over of moments – Stiffness and carry over factors – Analysis of continuous beams – Plane rigid
frames with and without sway – Naylor’s simplification.
