Module Leader: Prof. W.J. Lewis
Module Information
Scope
This 15 CATS module is one of the third year modules for:
| Core: | Optional: |
|
|
Aims
The design of concrete structures is a main stream activity of professional civil engineers. The subject, therefore, forms a principal part of civil engineering courses and is essential for professional accreditation. Structural engineering is a substantial economic activity; many concrete structures are of such a scale and complexity that they require extensive management for their procurement, maintenance and later reuse, or demolition.
Learning Outcomes
By the end of the module the student should be able to...
- Understand the background theory of design of concrete structures, have knowledge of principles of Limit State Design, and margins of uncertainty associated with loading, material properties and type of structural action.
- Analyse the response of main structural elements to a variety of load and boundary conditions.
- Examine critically the results of structural analysis and design of concrete sections; determine form and size of structural elements.
- Appreciate the relationship between design, durability, and ease of construction.
Syllabus
Design process; structural form and action; choice of material; uncertainties in design: partial safety factors. Limit States.
Revision of Moment Distribution method.
Re-distribution of elastic moments
Load combinations and patterns; shear and bending envelopes.
Design of reinforced concrete beams to ULS: design assumptions; resistance to bending; stress and strain blocks; design formulae for singly and doubly reinforced rectangular sections; examples.
Design of T- and L-beam sections in bending; examples
Design for shear; truss analogy; examples
Serviceability limit state (SLS): elastic theory; deflections, cracking; bond and anchorage; calculation and control of crack widths; examples
