DESCRIPTION - summary of the module content

This module builds on Mechanics (ECM1108) to further your understanding of mechanical behaviour of structures and its application to engineering design. You will enhance your mathematical analysis skills and develop ability to perform linear elastic analysis of beams and 2D frame structures. You will explore techniques underpinning structural analysis including strain energy, virtual work, and flexibility and stiffness 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.

Prerequisite module: ECM1108 or equivalent
 

AIMS - intentions of the module

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

 




 

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

This is a constituent module of one or more degree programmes which are accredited by a professional engineering institution under licence from the Engineering Council. The learning outcomes for this module have been mapped to the output standards required for an accredited programme, as listed in the current version of the Engineering Council’s ‘Accreditation of Higher Education Programmes’ document (AHEP-V3).

 

This module contributes to learning outcomes: SM1m, SM2m, SM3m, SM5m, EA1m, EA2m, EA3m, D1m, EP3m, G1m
