Steel-deck composite floor systems are being increasingly used in high-rise building construction, especially in Australia, as they are economical and easy to construct. These composite floor systems use high strength materials to achieve longer spans and are thus slender. As a result, they are vulnerable to vibration induced under service loads. These composite floor structures are normally designed using static methods, which will not reveal the true behavior under human-induced loads. The one-way spanning behavior of composite floor structures makes them even more vulnerable to vibration problems in contrast to conventional two-way spanning reinforced concrete floor slabs. Reinforced concrete floors will be stiffer and less vulnerable to vibration caused by human-induced loads.
