UNIT TITLE

Use basic structural analysis in engineering

APPLICATION

This unit describes the performance outcomes, skills and knowledge required to determine the internal actions of structural systems.

The unit of competency is applied by drafting personnel and technicians in a civil and structural engineering environment, operating as part of a design and/or construction team, to analyse structural integrity.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

• DCSMTH610 Use mathematics in engineering
• DCSSOM615 Use strength of materials in engineering

ELEMENT

Elements describe the essential outcomes.

PERFORMANCE CRITERIA

Performance criteria describe the performance needed to demonstrate achievement of the element.

1.    Use the moment distribution method to determine internal actions of a loaded statically indeterminate structural system.

1.1.      Model a structural system showing all loads.

1.2.      Determine distribution factors, fixed end moments and carry over factors in a structural system

1.3.      Perform a moment distribution analysis of a structural system.

1.4.      Construct axial force, shear force and bending moment diagrams using the results of the moment distribution analysis (in 1.3)

2.    Use the direct (matrix) stiffness method to determine internal actions of a loaded statically indeterminate structural system.

2.1.      Model a structural system showing all loads.

2.2.      Determine fixed end forces and moments and hence sketch solution 1.

2.3.      Remove loads and apply opposite to the fixed end forces and moments and solve to get solution 2

2.4.      Combine solution 1 and 2 to get a final solution

2.5.      Construct axial force, shear force and bending moment diagrams using the results.

3.    Use a structural analysis computer program to determine internal actions of a loaded statically indeterminate structural system.

3.1.      Model the structural system showing all loads.

3.2.      Enter appropriate data into a structural analysis computer program.

3.3.      Interpret results from the computer analysis to verify the validity of the analysis.

3.4.      Construct axial force, shear force and bending moment diagrams using the results of the computer analysis

4.1.     Determine the moment amplification factor.

4.2.     Modify the axial force, shear force and bending moment diagrams to account for the moment amplification factor.

TITLE

Assessment requirements for DCSBSA619 Use basic structural analysis in engineering

PERFORMANCE EVIDENCE

To achieve competency in this unit a person must satisfy the requirements of the elements and performance criteria, foundation skills and range of conditions included in the unit.

The person must also:

• develop and analyse at least 3 models of a structural system, using one model for a manual moment distribution analysis, one for a manual direct stiffness method, and one for computer analysis.
• convert a first order analysis into a second order analysis within the limits set out in Australian codes for hand calculations.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once for each criterion.

KNOWLEDGE EVIDENCE

To achieve competency in this unit, a person must demonstrate knowledge of:

• Key concepts and principles of structural analysis, including:
  • Use of relevant standards
  • theorems 1 and 2 of the area moment method.
  • formulae for fixed end moments for loaded beams.
  • basic matrix algebra and arithmetic
  • member stiffness matrices for axial, shear and bending loads.
  • the structure stiffness equation.
  • formulae to determine moment amplification factors.

ASSESSMENT CONDITIONS

Assessment conditions:

All assessment must be completed in accordance with work health and safety standards.

When assessments are conducted remotely, invigilation software must be used to ensure authenticity of work completed.

Model answers or marking guides must be provided for all assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.

The candidate must have access to all tools, equipment, materials and documentation required.

Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisation (RTOs) current at the time of assessment.

Assessors must also hold a tertiary qualification in engineering or related field.

Assessors must have worked for at least 3 years in industry where they have applied the skills and knowledge covered in this unit of competency.

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

The RTO must take appropriate steps, as an ongoing procedure, to verify information about trainer and assessor’s qualifications, vocational competencies and current industry skills
