Description
The module covers the following topics in theory and design of structures:
Theory:
2-d stresses, Mohr's circle
Yield and failure criteria in 2D and 3D
St Venant's principle
Buckling of struts
Plastic collapse
Energy methods – displacements in pin jointed frames and energy in bending
Moment distribution
Behaviour and analysis of two-pinned and three-pinned arches
Behaviour and analysis of cables
Design:
Introduction to limit state design
Steel – design of restrained beams, short and slender columns under axial load only
Reinforced Concrete – design of elements in flexure (single and double reinforcement), shear design of reinforced concrete beams, design of short columns subject to axial load only.
Learning Outcomes
By the end of the module students should be able to:
analyse a structural element under multi-axial stress
calculate the load capacity of single columns or struts subjected to axial load
explain the concept of limit state design
design a restrained steel beams, short or slender column to EC3
design a reinforced concrete element beam or short column to EC2
use moment distribution to analyse a continuous beam
analyse three pinned arches and appreciate the behaviour of two pinned arches under symmetric and unsymmetric loads
calculate strain energy due to axial force and due to bending in simple structures and use energy methods to calculate deflections in beams and simple pin-jointed frames.
apply the plastic method of analysis to beams and simple frames
explain the term shear centre and locate its position in a channel section
analyse cables subjected to transverse loads
explain the St Venaint's prinicple and its importance regarding the effect of localized stresses on structural behaviour
apply appropariate yield and failure criteria to deduce the safety of components subjected to complex stress states
