Abstract

This research has investigated the main parameters governing the design of tall timber buildings, including fundamental frequencies and local/overall lateral displacements of the building due to wind, and conducted structural analysis and design on main elements of the building under normal and fire conditions to the Eurocodes. Two 30-storey tall timber buildings constructed with either CLT only or combined CLT and glulam have been numerically analysed using commercial software SAP2000. Selected fire scenarios have been applied to the designed buildings and the reduced cross-section approach has been used to assess the fire resistance of the buildings for up to 120 minutes. Thus the residual internal forces/stresses and the corresponding fire resistances of individual CLT or glulam elements can be determined, and the global safety and stability can be assessed to eventually verify that the tall timber buildings will be safe enough under ambient loading conditions and specified fire scenarios.
