Synopsis

This unit covers the concepts of load and resistance, load factors and capacity factors, the design criterion for strength of structures, representation of loads on structures, the elastic response to applied loads of two dimensional framed structures, continuous beams and trusses, the concept of load path and equilibrium applied to framed structures, distinctions between braced and unbraced frames and their identification, flexural strength of beam cross-sections based upon idealised elastic-plastic material behaviour, up to ultimate strength, applied to steel beams of compact cross-section, flexural strength of beams based upon section capacity.

Outcomes

Knowledge

The concepts of load and resistance, load factors and capacity factors, and the design criterion for strength of structures representation of loads on structures. The elastic response to applied loads of two dimensional framed structures, continuous beams and trusses.

The concept of load path and equilibrium applied to framed structures. Distinctions between braced and unbraced frames and their identification. Flexural strength of beams based upon section capacity, excluding lateral buckling. Flexural buckling and strength of pin ended columns, with application to symmetric compact section steel columns. Interaction of axial force and bending moment in the ultimate strength of steel beam columns.

Skills

Analyse statically determinate frames and pin-jointed trusses by method of sections (and joint equilibrium for trusses). Analyse braced and unbraced frames using software Spacegass or Microstran. Determine moment-curvature relationship up to collapse of steel beams of compact cross-section. Determine capacity envelope for interaction of axial force with bending moment in compact steel beams, with extensions to asymmetric cross-sections. Visualise bending moment and shear force diagrams, and load paths through structures. Set up structural layouts for rectangular framed buildings. Use simplified structural modelling for initial sizing of members. Determine the envelope of maximum load effects on structures.

Attitudes

Through an engineering project that is within the students' life experiences (ie design of a multi-storey carpark), students should see the relevance of the study of this unit to their future careers. They will develop confidence in the use of standard analysis methods and computer software. Students will further develop their group work and communication skills (particularly in report writing).
