UNIT I 
FLEXIBILITY METHOD 
Equilibrium and compatibility – Determinate vs Indeterminate structures – Indeterminacy - Primary
structure – Compatibility conditions – Analysis of indeterminate pin-jointed plane frames,
continuous beams, rigid jointed plane frames (with redundancy restricted to two).

UNIT II 
STIFFNESS MATRIX METHOD 
Element and global stiffness matrices – Analysis of continuous beams – Co-ordinate
transformations – Rotation matrix – Transformations of stiffness matrices, load vectors and
displacements vectors – Analysis of pin-jointed plane frames and rigid frames (with redundancy
limited to two)

UNIT III
 FINITE ELEMENT METHOD 
Introduction – Discretisation of a structure – Displacement functions – Truss element – Beam
element – Plane stress and plane strain - Triangular elements
