Application of Timber-lightweight Composite Structures for Floor Construction

01.03.2010 - 30.09.2012
Research funding project
Timber-lightweight concrete composite systems form a low-cost solution to renovate existing timber floors. The increased stiffness and strength are such that higher floor loads are permissible or decreased deflections are obtained. The structural behavior of timber-lightweight concrete composite members is governed by the shear connection between them. The key objective of the research project is to provide and facilitate new possibilities for timber-lightweight concrete structures in construction. The use of timber-lightweight concrete products is to be supported and stimulated by comprehensive and scientifically robust background data, which is presented in user-friendly and adapted tools for engineers. The lightweight wood-concrete construction systems allowed: Use of wood both as permanent formwork and as concrete reinforcement; Reduction of the dead load and increasing the thermal insulation; Minimization of the dimensions of the timber and concrete components; Creation of environmental-friendly construction made of renewable resources; Reduction of energy consumption by using low-energy materials and energy-efficient systems
