Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

• Ability to apply the principles of structural mechanics, analysis to solve plane for forces and displacements in statically determinate beams and/or trusses and demonstrate knowledge of and ability to apply the principles of simple dynamic systems to the solution of plane vibration/oscillatory problems (LO’s 1-7)

• Ability to create appropriate analytical models (using a suitable commercially available software package) of simple skeletal structures, such as continuous beams and/or frames and trusses and to be able to appropriately verify and valid the model and results obtained (LO’s 4 and 5)

• Ability to present engineering calculations with appropriate us of data and presentation of data in tables and graphically (LO’s 8-11)

Thus, the summative assessment for this module consists of:

• Examination [Learning outcomes assessed: 1-7] (2 hours, 80%)

• Structural Analysis Assignment (12 hours) [Learning outcomes assessed: 4 and 5] (15 hours, 10%); Mechanics and Dynamics Quizzes (4 online short quizzes) [Learning outcome assessed:  1-3 and 6-7] (4 hours, 10%)

Formative assessment and feedback

Formative assessment and feedback is provided via the weekly supported tutorial work  (15 hours).  The students complete a set of worked solutions to a range of questions in the tutorial classes and are provided with tutor support in comment and feedback in the sessions.

Module aims

• The deformability of structures and the principles of the elastic analysis of statically determinate structural forms
• Slender strut buckling and introduce the instability collapse behaviour of structures under in-plane compressive loads
• The analysis of statically indeterminate beams and simple no-sway frames
• The use of structural analysis software – modelling and interpretation of behaviour
• The dynamic response of free and forced vibration of a single degree of freedom un-damped and damped systems

Methods of Teaching / Learning

Learning and teaching strategy:

The module provides the basis for structural analysis related topics in Structural Engineering at FHEQ Level 5, 6 and 7 on the MEng and BEng programmes in Civil Engineering.  It extends the curriculum to include deformability, basic stability and statical indeterminacy of structural form, an introduction to basic structural vibration and provides an introduction to use of computer based structural modelling, including steps of validation and verification.  This builds on the fundamentals covered in ENG1063 and ENG1076 at FHEQ Level 4 of the programmes.  The basic concepts of dynamic behaviour are also introduced.

Learning and teaching methods:

The module is delivered by weekly lectures and supported by tutorial classes (smaller groups) in the three main components:

• Mechanics lectures (9 hours) and tutorials (4 hours)

• Structural Analysis lectures (10 hours) and tutorials (4 hours)

• Dynamics lectures (6 hours) and tutorials (3 hours)

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
