What is Structural Engineering?

Structural engineering ensures reliability of structures to perform its intended function. Minimum reliability of structures to perform its intended function is compliance to the structural sections of the BCA (Building Code of Australia) which is a statutory requirement. A house compliant to current BCA structural requirements: - Have a minimum design life of 50 years with 95% reliability. - Can resist the expected 5 second wind gust that occurs once in every 500 years. - Can resist an additional 50% of the rated loads. - Have floors generally rated to 150kg/m2 or 180kg. - Have balcony floors more than 1m above ground level rated to 200kg/m2 or 180kg. - Have ceilings rated to 50kg/m2. - Have roofs rated to 25kg/m2 or 110kg. Client contracts may add additional structural requirements for improved performance more than the BCA minimum requirements. It is recommended to advise your structural engineer of any special structural requirements that you may have. For example; preferred performance level more than the minimum BCA requirements, design life, time until first maintenance, vibrations, etc. A structural engineer ensures reliability of structures to perform its intended function by: - Conducting design calculations using proven and generally accepted mathematical and scientifical literature to achieve the structural requirements. - Providing written and diagrammatic instructions for construction. - Inspecting and confirming the structural elements of the construction at critical stages. - Providing certications of compliance and limitations of compliance (if any) for assurance purposes. - Providing structural reports to facilitate decision making if required or requested.
