CENV2031 Structural Analysis

Module Overview

This module is aimed to develop and deepen knowledge already gained in FEEG1002 of understanding of how structural elements behave, and can be analysed. The module provides a firm basis for all subsequent modules in these areas in later years.

Aims and Objectives

Module Aims

• Extend understanding of how structures behave, and can be analysed. • Provide students with a broader and deeper understanding of statics, including topics on the concept of safety factor and its application, three-pin arches, biaxial bending with axial force and torsion of thin, non-circular shafts • Explain the elastic analysis of statically indeterminate structures, and to show key implications of redundancy. • Understand the use of plastic theory for analysis of structures.

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • The distributions of strain and stress in a beam due to bending and/or shear
  • Find lower bound estimate of the failure load of beams.
  • Solve stability (i.e. buckling) problems of columns.
  • The distributions of stress in thin-walled, non-circular shafts under torsion
  • Understand the concept of superposition, and how it is used to combine stresses in a member under more than one load effect, e.g. beam with axial load
  • How to solve three-pin arches
  • The concept of safety factor
  • Analyse statically indeterminate truss, beam and frame structures.
  • Apply matrix method, slope-deflection method, moment distribution method and force method of analysis of structures.
  • Apply the Tresca and von Mises yield criteria.
  • Find upper bound estimate of the failure load of beams and frames.
Subject Specific Intellectual and Research Skills
