Experimental assessment of static and dynamic properties of a new sustainable composite floor

Currently growing interest in use of timber-concrete composite (TCC) floor systems indicates thatthey can be an effective alternative to traditional concrete floors and an efficient solution for rehabilitatingexisting timber floors. This study aims to experimentally verify a novel sustainable timbersteel-concrete composite floor system implemented in a real building. The system's performance wasassessed under static and dynamic loads, with a particular focus on the impact of longitudinal joints,before and after they were grouted. Static tests used IBC water tanks to apply a 3 kN/m² load, anddeflections were measured with LVDTs and a levelling instrument. Dynamic tests involved measuringeigenfrequencies under self-weight and additional loads, and impact loads. The experimentsdemonstrate the effectiveness of grouting joints in enhancing the structural performance of the compositefloor system, reducing deflection, and improving dynamic response.
