Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

EDX130 - Use mathematics at technician level
EDX140 - Use quadratic, exponential, logarithmic and trigonometric functions and matrices
EDX100 - Solve simple problems in Statics and Strength of Materials
EDX090 - Solve more complex problems in Statics and Strength of Materials
EDC030 - Determine design loads on beams and columns

Course Description

This unit covers the competency to interpret Australian Standards and design simple timber structures consisting of beams, columns and connections.

National Codes, Titles, Elements and Performance Criteria

 National Element Code & Title: EAC140 Analyse and design simple structural timber members Element: Calculate, using Appropriate Australian Standards, the design loads for timber beams and columns Performance Criteria: 1.1 AS1170 Part 0 is used to determine load combinations. 1.2 AS1170 Part 1 is used to determine the design dead and live loads. 1.3 Calculations are carried out to determine the loads on beams. 1.4 Calculations are carried out to determine the loads on columns. 1.5 AS1170 Part 2 is used to determine the wind loads on structural members. Element: Design, to AS1720, simple timber beams, simple timber beams within a grid, columns and nailed and bolted connections. Performance Criteria: 2.1 Calculations are carried out to design a simply supported beam for strength. 2.2 Calculations are carried out to design a simply supported beam for shear. 2.3 Calculations are carried out to design a simply supported beam for serviceability - short and long term. 2.4 Calculations are carried out to design a column for concentric load. 2.5 Calculations are carried out to design structural members subjected to tensile forces. 2.6 Calculations are carried out to design simple nailed and bolted connections.

Learning Outcomes

• Calculate, using Appropriate Australian Standards, the design loads for timber beams and columns
• Design, to AS1720, simple timber beams, simple timber beams within a grid, columns and nailed and bolted connections.

Details of Learning Activities

Theory and industry-based worked examples on the:
• Calculation of the design loading for timber beams and columns using appropriate Australian Standards and industry drawings
• Analysis and design of simple timber beams in accordance with AS 1720 and industry drawings
• Analysis and design of axially loaded timber compression members in accordance with AS 1720 and industry drawings
• Analysis and design of timber tension members and industry drawings
• Analysis and design of nailed and bolted connections in timber in accordance with AS 1720 and industry drawings

Research
• Using the Internet research AS/NZS 1170 Part 0, 1 & 2 and identify the clauses required for the acceptable design loading for timber beams and columns.
• Using the Internet research AS 1720 and identify the clauses required for the design of simple timber beams, tension members, compression members and nailed and bolted connections.

Overview of Assessment

This unit will be assessed in the classroom and the laboratory environment using holistic assessment based on typical workplace activities.

Assessment will comprise (for both elements):

• A project based upon the analysis and design of timber members in a 3-D structural frame
• Two 2-hour examinations (mid-semester and end-of-semester)
