ABSTRACT
Excessive deflection should not impair the function of the structure or be aesthetically unacceptable. Cracks should not be unsightly or wide enough to lead to durability problems and vibration should not cause distress to the structure or discomfort to its occupants. AS3600-2009 states: “Design checks shall be carried out for all appropriate service conditions to ensure the structure will perform in a manner appropriate for its intended function and purpose”.
