Latest Developments of Wood and Wood-Hybrid Systems in Midrise and Highrise Building Applications

摘要

In North America, light-frame wood construction that originated in the 19th Century wasrnand still is the dominant system for single family and low-rise (up to four story)rnbuildings. Recently, this system is increasingly used for midrise construction. Forrnexample, about half of the 5 to 7 story midrise buildings in the US are being constructedrnwith light wood frame exclusively or in combination with other systems (i.e. hybridrntechniques).rnIn high-rise applications (more than 7 stories), on the other hand, heavy timber systems,rnonce reaching as high as 9-storeys at the beginning of the 20th Century, but lost favor withrndevelopers when steel and concrete systems were introduced.rnAfter missing almost an entire century, the increased interest in a more sustainable builtrnenvironment and the aesthetic qualities of wood have led to the creation of new knowledgernon “mass timber “ and “hybrid”, which will enable wood to again make in-roads into highrisernapplications.rnThe presentation will include examples of midrise and highrise wood building applications,rnboth from the past and present, and hope this will inspire the next generation of woodrncomposites.
