Advanced Structural Analysis

(a) Discuss the various steps to be followed while analysing structure by stiffness matrix method.
(b) Generate flexibility and stiffness matrices by illustrating corresponding co-eflicients for the beam shown in Fig. 1 and subjected to loads A1 and A, at the free end.
(c) A solid circular plate of radius 0.25 m with its outer edge completely restrained is subjected to a pressure load of 7 MPa. If the allowable stress in the plate is limited to 90 MPa. Determine (i) the thickness of the plate (ii) the maximum deflection.
Assume E = 200 GPa, ii = 0.3.

(d) A prismatic folded plate ABCDEF shown in Fig.6 supports a live load of 0.4 kN/m2 in addition to the self weight. Estimate the stresses developed in the plate at mid span sections if the plates BC, CD and DE are 120 mm thick and the plates AB and EF are 250 mm thick. Span of the folded plate = 8 m. Assume unit weight of plate = 24 kN/m3
