The aim of the project is to improve the design, cost and material efficiency of wood hybrid mezzanine floors for wooden buildings.


The aim will be achieved by combining user satisfaction in timber buildings, field measurements of timber buildings, laboratory testing of suspended floor solutions and consideration of these sub-sets in the optimization of solutions and design development. One objective of the project is to provide research data on the differences between measured and calculated characteristic frequency values. The project will create a new type of sizing tool for designers, to facilitate and simplify the design of suspended floors.



WP 1 Preparations, field measurements and surveys

WP 2 Development of measurement technology

WP 4 Test structure manufacturing and testing new solutions
