WOOD WISE 10 fun facts about wood and hybrid structures Hybrid structures combine the best properties of each material used in construction to achieve efficient solutions for complex designs. 1 Many buildings don’t suit the ‘one size fits all’ criteria and this applies to building materials too. Hybrid construction takes the best qualities from each material. 2 Wood is used extensively in construction yet sometimes it’s necessary to combine wood with other materials such as steel or concrete to create a hybrid structure. 3 Hybrid construction is particularly common when building large or tall structures such as apartment blocks, offices, visitor centres or schools to provide extra structural support. 4 Timber engineered wood products feature heavily in hybrid structures including Cross Laminated Timber (CLT), Glued Laminated Timber (Glulam) and Laminated Veneer Lumber (LVL). 5 Hybrid structures often result in aesthetically pleasing, cost effective and sustainable buildings. Designs can be as simple or complex as needed and hybrid construction is particularly beneficial for more complex designs. 6 Hybrid structures are often made up of elements constructed off site, which means faster build times and is it well received in built up areas as it creates less disruption, noise and mess. 7 Hybrid structures achieve structural efficiency and often a reduction in carbon footprint. Hybrid structures are also an economical, architectural, sustainable and structurally feasible alternative. Initial costs may seem high but the speed of construction balances this out. 8 Wood is great for compression and steel is great for tension and when combined they make an extremely sturdy building. 46 JUNE / JULY 2019 // By Wood for Good Hybrid construction is common in large or tall structures. 9 10 A common use of wood in hybrid structures is a timber roof structure on steel panels or timber floor panels with a steel structural frame, which is an alternative to concrete. Wood and steel can be left exposed, creating a beautiful structure. Wood and concrete work well together with concrete often providing the foundations and service core. Waste materials can be included within concrete mix and using precast concrete can speed up the construction process. www.timberiq.co.za
