Credit Points: 12.5 Credit Points

Related Course/s:

A unit of study in the Bachelor of Engineering (Civil Engineering) and Bachelor of Engineering (Civil)/Bachelor of Commerce.

Aims & Objectives:

This unit aims to provide students with knowledge and skill to analyse indeterminate structures using a variety of methods such as flexibility and moment distribution and to design reinforced concrete structures.

After successfully completing this unit, students should be able to:

• Determine the statical degree of indeterminacy for beams, frames and trusses
• Use the virtual work method to calculate deflections
• Apply the flexibility method to analyse indeterminate beams and frames
• Apply the moment distribution method to analyse indeterminate beams and frames
• Recognise the basis for current codified structural design philosophy
• Specify the constituents of concrete and its properties
• Design reinforced concrete beams, one way slabs and columns
• Work effectively in small groups to design a reinforced concrete structure considering different loading actions, serviceability and ultimate limit states

Teaching Methods:

Lectures (24 hours), Tutorials (18 hours), Laboratory classes (2 hours) and Design classes (4 hours)

Assessment:

End of Semester examination (50-70%) and assessment during semester (tests, laboratory reports assignments) (30-50%)

Generic Skills Outcomes:

• Ability to apply knowledge of basic science and engineering fundamentals
• Ability to undertake problem identification, formulation and solution
• Ability to utilize a systems approach to design and operational performance
• Ability to function effectively as an individual and in a multi-disciplinary and multi-cultural teams, with the capacity to be a leader or manager as well as an effective team member
• Understanding of professional and ethical responsibilities and commitment to them
• Expectation of the need to undertake lifelong learning, and capacity to do so
