Dynamical Response of Steel Deck Composite Slabs with Geometric Orthotrophy Subjected to Human Rhythmic Activities

摘要

The competitive trends of the world market have long been forcing structural engineers to develop minimum weight and labour cost solutions. A direct consequence of this new design trend is a considerable increase in problems related to unwanted floor vibrations. This phenomenon is very frequent in a wide range of structures subjected to rhythmic dynamical loads, generally caused by human activities such as: musical, sporting events, dance or even gymnastics. The main objective of this paper is to incorporate the orthotropic solution for the concrete slabs with steel decks subjected to rhythmic dynamical actions. This investigation focused on the use of different steel deck geometries and their influence in the dynamical response of commonly used composite floors.
