Dynamic Behaviour Of LVL-Concrete Composite Flooring Systems

An LVL-concrete composite floor (LCC) is a hybrid flooring system, which was adapted from a timber-concrete composite (TCC) floor system. By replacing the timber or glulam joists with LVL joists, the strength of the floor was increased. However, the demand nowadays is to build longer spans and this may reduce the stiffness and lead to the floor being more susceptible to vibration problems. While the vibration problem may not be as critical as other structural issues, people could feel sick and not comfortable if the floor vibrates at the resonant frequency of the human body. Hence, this research focuses on the dynamic behaviour of long span LCC flooring systems. Experimental testing and finite element modelling was used to…
