Prerequisites: CS2001 CS2003 MA2000
39 lectures, 26 tutorials, 13 hours practicals. First semester.
Available to civil engineering students.
Determinate structures Conditions for determinacy and stability. Elastic deflections of beams, frames and trusses; conjugate beam, virtual work, strain energy; Castiglianos theorems; Bettis law, Maxwells law; Muller-Breslaus principle; influence lines.
Indeterminate structures Solutions for beams, frames and trusses using the principle of superposition (force method); superposition equations. Sign convention. Slope deflection equations; sidesway; introduction to moment distribution (no sidesway).
Matrix displacement method Outline of force and displacement methods. Displacement method; degrees of freedom. Member and total structure stiffness; truss and frame element; assembly of total structure stiffness; direct displacement method; force-displacement relationship; solution for displacements, external reactions and member forces. Statical condensation; analysis by sub-structures; general loads.
Learning Objectives:
- develop the ability to calculate deflections in beams, frames and trusses using conjugate beam, virtual work or energy methods as appropriate;
- a detailed understanding of the fundamental theory of the matrix displacement method;
- an ability to solve a variety of indeterminate beam, frame and truss problems.
Assessment by examination (50%-70%); on-course assessment (30%-50%).
