MODULE TITLE CREDIT VALUE Structural Behaviour 15 ENG2012 Dr Andres Felipe Alonso Rodriguez (Coordinator)
DURATION: TERM 1 2 3
DURATION: WEEKS 11
 Number of Students Taking Module (anticipated) 160
DESCRIPTION - summary of the module content

This module builds on the mechanics component of Fundamentals of Mechanics, Materials and Electronics in first year and Solid Mechanics in second year. You will further your understanding of structural analysis and its importance to engineering design. You will develop cornerstone skills, essential for civil, structural and mechanical engineers. You will enhance your mathematical analysis skills and develop ability to perform linear elastic analysis of beams and 2D frame structures both quantitatively and qualitatively. You will explore techniques underpinning structural analysis including strain energy, virtual work, and flexibility methods. You will also investigate instability and plastic collapse mechanisms of simple structures. You will further develop your experimental skills and awareness of health and safety practice within engineering.

AIMS - intentions of the module

This module addresses topics that are essential to the design and understanding of the behaviour of engineering structures under static loading. The module will provide a mathematical basis for quantitative analysis (including calculating internal forces, reactions, deflections, rotations, buckling capacity and plastic collapse) as well as qualitative analysis of beams and frames. It will lay the foundations for more advanced structure design modules.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

Discipline and Module Intended Learning Outcomes:
On successful completion of this module, you should be able to:

ILO.1 - Explain and utilise strain energy methods

ILO.2 - Calculate the critical buckling load for struts under compression

ILO.3 - Evaluate the maximum plastic moment of beams with simple cross sections (rectangular or I-beams)

ILO.4 - Estimate the plastic collapse load of simple 2D structures

ILO.5 - Perform qualitative structural analysis of beams and 2D frame structures

ILO.6 - Calculate the deflection in statically determinate and indeterminate prismatic and non-prismatic beams

ILO.7 - Use virtual work to find unknown reactions, bending moments, deflections and rotations in statically determinate 2D structures

ILO.8 - Employ the flexibility method to find bending moments in statically indeterminate 2D structures

ILO.9 - Demonstrate an ability to make appropriate assumptions to model real-life engineering problems

ILO.10 - Demonstrate improved experimental skills and awareness of health and safety practice in laboratory classes

ILO.11 - Show increased ability with mathematical analysis and in particular its application to solving problems

ILO.12 - Illustrate developed problem solving and presentation skills
