*****

PART ?A (22 Marks)1. a) Explain the rank deficiency of a matrix. [3]
b) What are the characteristics of a beam element? [3]
c) Distinguish between the element and global stiffness matrices. [4]
d) What is a grid element and generate the stiffness matrix of a grid element? [4]
e) Explain the significance of sub-structuring. [4]
f) Differentiate a frame element and a truss element. [4]

PART ?B (3×16 = 48 Marks)2. a) Explain degrees of freedom of different types of structural elements. [8]
b) Explain the static and kinematic indeterminacy of various structural
components.
[8]

3. a) Derive the stiffness matrix of a two noded truss element of length ?L, and axial
rigidity ?AE?.
