Getting on Deck: High-performance options for composite decking

Since the late 1980s, manufacturers have introduced dozens of wood-plastic composite decking products, including composite boards with thin plastic caps (i.e. capped composites) in recent years. Composite decking manufacturing methods vary, resulting in deck boards with significantly different performance characteristics. Several composite brands have experienced field failures, but newly advanced products are proving promising against demanding exposures. Specifying durable and attractive composite decking requires attention to key physical traits, including moisture absorption, and insect resistance.

Specifying Steel Fibers for Concrete Floors

Thin, short strands of steel are being increasingly specified as reinforcement in ground-supported slabs and in composite steel deck-slabs. Structural engineers are still figuring out how best to design with these components, but specifiers need to think about how to define this material in the contract documents. Dosage is critical, for one thing, but not all fibers are alike. Without specifying other key details, one can end up with concrete that contains the specified mass of fibers, but does not fulfill the designer’s intentions.

LCT ONE is an eight-story, timber-based sustainable building developed in Austria in 2012. The goal of the project was to develop a flexible, high-performance, prefabricated construction system as a new product, which meets all technical and economical requirements of modern real estate markets. The project is based predominantly on a renewable resource—wood, with additional emphasis placed on resource and energy efficiency. The project is meant to demonstrate to the building industry that there are new timber technologies and industrial processes where a modern, system approach to construction can be applied.
