SECTION A – Short Answer (Attempt All)
Focus: Definitions, concepts, and direct theory (2 marks each)
Important Topics & Notes
Indeterminate Structure: Structure with unknown reactions > equilibrium equations.
Influence Line: Graph showing variation of response (reaction, SF, BM) at a point due to a moving load.
Degree of Indeterminacy: Difference between unknown forces and equilibrium equations.
Two-Hinged Arch: Hinges at supports, indeterminate to degree 1.
Two-Hinged vs Three-Hinged Girders: Three-hinged is statically determinate; two-hinged is indeterminate.
Local Coordinate System (Matrix Analysis): Member-based axes used for stiffness formulation.
Plastic Moment Capacity (Mpl): Moment at which full plastic hinge forms.
Tip: Write crisp definitions + one key property.
