Aims: Development of matrix methods of analysis and computer techniques for structural analysis. To advance the student's knowledge and ability in the plastic analysis of structures, including multibay frames.
Learning Outcomes:
On successful completion of the unit, the student will be able to analyse complex structural systems, and design steel and concrete structures using plasticity-based approaches.
Skills:
An ability to analyse elastic structures using advanced techniques, including finite element analysis. An ability to design and analyse ductile steel and concrete structures using plasticity theory.
Content:
Matrix Methods: stiffness analysis of pin-jointed space trusses and rigidly jointed frames. Organisation of stiffness method for computation. Introduction to finite element method. Plane stress and plane strain elements. Plastic analysis of frames: Upper and lower bound solutions. Instantaneous centres, combined mechanisms for multibay and multistorey frames. Reinforced concrete: beams - T beams, doubly reinforced beams. Slabs - two way span slabs, flat slabs, strip theory, yield-line theory, membrane action, bridge assessment. Columns - combined compression and bending, compression and tension control, derivation of design graphs, moment increase due to slenderness.
