Special IASS 2024_Applications of Spatial Timber Structures in China and Research on The Performance of Their Typical Connections

Timber, being a versatile and sustainable material, has been used for residential and public buildings throughout history. In recent years, advancements in engineering and construction technology have resulted in the development of innovative timber spatial structures that push the boundaries of traditional timber construction. Especially, numerous spatial timber structures have been constructed in China in recent years. This study aims to provide an overview of notable examples of spatial timber structures in China, including their architectural features, structure arrangement and construction method. Additionally, the configuration of some timber connections utilized in the Taiyuan Botanical Garden project are analyzed and the mechanical behavior of connections are investigated by a brief introduction of experimental tests. The research will provide a reference for engineering design of spatial timber structures in the future.
