Abstract: This paper comprises an experimental investigation into the structural performance of cold formed steel (CFS) and timber board composite floor systems. The tests include a series of small-scale pushout tests and full-scale bending tests carried out using a refined loading system to simulate uniformly distributed constant load. The influence of connection details (screw spacing and adhesives) on floor performance was investigated. The results are then compared to predictions from relevant existing models for composite floor systems. The results of this research demonstrate the significant benefits of considering the composite action of the boards in floor design. Depending on connection detail, an increase in flexural stiffness of up to 40% was observed in the floor system, when compared to designing joists individually.
Abstract: The paper reports on the subject of recycling and
further use of secondary raw materials obtained from solar panels,
which is becoming a very up to date topic in recent years. Recycling
these panels is very difficult and complex, and the use of resulting
secondary raw materials is still not fully resolved. Within the
research carried out at the Brno University of Technology, new
polymer materials used for industrial floors are being developed.
Secondary raw materials are incorporated into these polymers as
fillers. One of the tested filler materials was glass obtained from solar
panels. The following text describes procedures and results of the
tests that were performed on these materials, confirming the
possibility of the use of solar panel glass in industrial polymer
flooring systems.
