This course builds on previous courses to introduce students to real structures as assemblies of members and elements, including how they are connected. Types of loading, the probabilistic basis for both self-weight and applied loading and the concept of design limit states will lead to calculation of loading for stability, strength and; serviceability limit states, based on Australian Standards. The concept of load paths and the requirement for stability, strength and stiffness for both braced and un-braced (sway) framed structures are introduced. This knowledge will be applied to the design of simple steel frames, to calculate member sizes or capacity in tension, compression, shear and bending and the connections required to create a practical structure, based on Australian Standards. This course will prepare students for subsequent courses in the structural design of statically indeterminate steel frames and structural design in other materials, structural systems or forms.

This course provides training to undergraduate students with the fundamental method of analysis and design of Structural Steelwork. The design of structural steelwork is way different from that of other structures, in which the stability design due to geometric nonlinearity (or slenderness) is more critical than their structural strength design. Connection details are also very different from that in the design of RC (and other) structures. By taking this course, students will be equipped with the essential skills to design structural steelwork including simple axial load members, flexural members, combined axial load and flexural members, simple portal frame, connection details and the use of commercial software for the structural analysis. The fourth-order ordinary differential equation for the Lateral Torsional Buckling (LTB) of flexural beam will be derived in this course. All design details are per AS4100-2020.

Course requirements

Assumed background

It is assumed that students have already passed statics and a basic structural analysis course, are familiar with the stresses, bending moment and shear force diagrams and are capable of calculating the reactions and forces on a freebody using equilibrium equations.

Aims and outcomes

The aim of this subject is to provide a solid foundation in the behaviour and limit states design of steel structures. In this course within the framework of steel, different design methodologies are discussed, a range of loading actions are described and different design strategies are taught. The subject is the first one in civil engineering program that provides the basic knowledge and skills required for structural designs and paves the way for more advanced courses that will be taught in later years of the civil engineering program.

Learning outcomes

After successfully completing this course you should be able to:

LO1.

Explain the chronological developments in the design methods and how to work with the Limit States Design (LSD) method.

LO2.

Discuss the presence, importance, types and use of standards and codes of practice relevant to structural design in Australia. This will include the ability to calculate loads applied to structures based on relevant Australian codes and standards.

LO3.

Explain the behaviour of steel as a material with specific properties and explain how this behaviour affects the development of design methods.

LO4.

Design steel elements in tension, compression, bending and combined actions using AS4100 (Australian Standards for the Design of Steel Structures) and be able to explain the theories behind the design methods in simple terms using visual models.

LO5.

Be able to relate the learning activities in the class to the real world applications, and discuss the ethical and legal obligations of a structural engineer.
