Course description |
This course build upon the basic principles of structural mechanics learnt in Structural Mechanics 2A. It investigates more complex types of structure, and focuses upon structural mechanics in a civil engineering context. The course describes the behaviour of beams under complex and combined loads (including moving loads), the 2D mechanics of materials, the buckling of simple columns, introduces elasto-plastic and plastic sectional analysis, and introduces the analysis of indeterminate structures. |

Summary of Intended Learning Outcomes
By the end of this course, the student should be able to:
- determine the deflected shape of beams under a variety of loads;
- draw simple influence lines for moving loads and moment envelopes due to combinations of loads;
- analyse two dimensional truss structures;
- evaluate how a simple column will buckle under a variety of end restraints, and demonstrate understanding of buckling in real structures;
- understand the concept of structural redundancy, and analyse simple statically indeterminate structures using the principle of superposition;
- determine the behaviour of elastic materials subjected to two-dimensional stress states, including the 2D elastic constitutive relationships and Mohr&©s Circle for stress and strain transformation in 2D; and
- apply the von Mises and Tresca yield criteria for 2D and 3D stress conditions. |
