Stateoftheart Research of Tall Wood Buildings

Abstract:

Stateoftheart research and application advance on tall wood buildings are summarized based on the current research situation abroad. Specially, an innovated engineering wood product, crosslaminated timber (CLT) is emphasized for its rolling shear property, which is the dominant factor of outofplane capacity. The key issues on tall wood buildings, such as structural systems, seismic and wind resistance, connection capacities, as well as fire resistance are expatiated. On account of reviews of the latest study, this paper indicates that the connection of members, load path and force distribution in structural systems are the key points of future research. Meanwhile, research on fire resistance of tall wood buildings can learn some experience from lowrise and multistorey wood buildings, but the height of building and the quantity of residents should be especially concerned. Finally, research prospects on development of Chinese tall wood buildings are proposed, and the key issues are analyzed and summarized.
