CENV6086 Advanced Structural Engineering

Module Overview

This module covers advanced aspects of structural engineering including: the design of box-girders for long-span bridges; steel-concrete composite beams and girders for bridges and buildings; prestressed concrete for bridges and buildings; the design of reinforced concrete subject to stress concentrations and the control of cracking in reinforced concrete. You will be taught the theory of design from first principles but in the context of the Eurocodes and an emphasis is placed on your learning approximate methods of design that can be used to compliment and check the output from Finite Element Analysis.

Prestressed concrete design: • Formulation of the design inequalities at transfer of prestressing force and under serviceability loading • Determination of the minimum section depth and the permissible range of tendon forces • Calculation of the permissible width of the cable zone • Quantification of losses of prestress caused by anchorage draw-in, elastic shortening, friction, shrinkage and creep. • Estimation of deflections at transfer of prestress and under the full SLS loading • Calculation of the ultimate limit state bending strength and shear strength • Control of bursting stresses for post-tensioned concrete anchors Thin Walled Structures: • Theory of buckling of unstiffened isotropic plates subjected to in-plane loading • Calculation of shear buckling stresses in the webs of plate girders • Design to prevent buckling of thin plates in compression • Assessment of the combined effects of torsion, shear and compression on buckling strength • Assessment of the effects of lack of straightness and residual stresses on buckling capacity The design of reinforced concrete to resist concentrated loads and stress concentrations • You will learn how to formulate and assemble strut and tie models which have a wide range of potential applications • You will learn about the different node types and strut types and corresponding limiting stresses • You will learn how to check the stresses in the struts and how to design the reinforcement for the ties and you will apply this theory to a range of case studies from bridges and buildings Prediction and control of movements in buildings: • Review case studies from real structures where movements have resulted in severe cracking • Understand the different causes of movements in structures • Calculate movements due to shrinkage, creep, elastic shortening, temperature and solar radiation effects • Understand the sources of restraint to movement and how these influence cracking • Calculate crack widths Composite construction: • Calculation of deflections in propped and unpropped composite beams • Approximate methods for assessing dynamic response of long-span composite beams subjected to footfall induced vibrations • Calculation of the elastic and plastic moment capacities of propped and unpropped composite beams • Design of shear studs using elastic and plastic methods

Learning and Teaching

Teaching and learning methods

A total of 36 lectures over 12 weeks. A range of design examples will be presented to explain the application of the theory to real design situations. An extensive range of tutorial questions will be provided for each topic and these will be accompanies with solution sheets which will enable you to practice and develop your understanding in preparation for the examination.
