EDX100B – Analyse force systems (basic)

Course Description

This unit covers the competency to use the Australian Standard AS 1170 to determine and to calculate different kinds of loadings on structural elements and to perform analysis of beam and column structures involving calculation of such features as support reactions, shear and bending moments.

National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:	EDC030B Determine design actions and analyse structures
Element:	Use AS1170 Parts 0 & 1 to calculate dead load and live load on simple structural elements Use the simplified procedure from AS1170 Part 2 to calculate wind load on simple structural elements Calculate loading on structural elements due to liquid pressure Carry out a detailed analysis of a simply supported beam including calculations for simple bending, shear, deflection, local buckling and lateral buckling Carry out a detailed analysis of a structural member subject to compression loads Carry out analysis of continuous beams Carry out analysis of simple rectangular frames Calculate the distribution of forces at joints in accordance with the elements’ stiffness Write a technical report
Performance Criteria:	1.1 Appropriate data is extracted from AS 1170 Part 1 1.2 The appropriate value of dead load and live load is calculated for given conditions. 1.3 The combined effect of dead load and live load is calculated using the relevant load combinations from AS 1170 Part 0. 2.1 AS 1170 Part 2 is used to extract relevant data related to wind loading. 2.2 The wind load on a structural element is calculated using the simplified procedure from AS 1170 Part 2. 3.1 Given relevant data, the resultant force due to fluid pressure on a structural element can be calculated. 3.2 The line of action of the resultant force and moment created is calculated. 4.1 The bending strength of a simply supported beam can be calculated – including simple bending stress, local plate buckling and lateral buckling. 4.2 The shear strength of a simply supported beam can be calculated. 4.3 The deflection in a simply supported beam can be calculated. 5.1 The buckling strength of a simple compression member can be calculated given the end and intermediate restraints. 5.2 The effective length and restraint conditions can be determined from a structural drawing for a compression member. 6.1 The member forces in a continuous beam can be calculated. 6.2 The redundant forces in a simple continuous beam can be calculated using work-energy principles. 7.1 The member force in a simple rectangular frame restrained against sway can be calculated. 7.2 The moment distribution method can be used to analyse simple sway restrained and non-restrained structures. 8.1 Given length, E,I and end conditions for a simple beam column connection in a rectangular frame, the distribution of moments can be calculated. 9.1. All data, assumptions and calculations including diagrams are written up in a short technical report.

Overview of Assessment

Assessment will incorporate a variety of methods including in-class and home study exercises, written tests, practical problem-solving exercises and, where appropriate, group submissions. Students are advised that they are likely to be asked to personally demonstrate their assessment work to their teacher to ensure that the relevant competency standards are being met.

Assessment Tasks

This course will be assessed in the classroom environment using holistic assessment, based on typical workplace activities.
Assessment will comprise the following :
• A project covering elements 1, 2 & 9 - a 3 dimensional building frame using industry drawings.
• An assignment covering element 3 & 9 - a retaining wall subjected to liquid pressure
• An examination covering elements 1, 2 & 5
• An examination covering elements 4, 6, 7 & 8
