N2 - This paper describes a computational framework that performs automated structural design of tall timber buildings at the resolution of conceptual design while considering typical loads and load combinations, material properties, and a set of architectural requirements. The framework is used to assess a range of tall timber geometries in terms of feasibility for different fire design approaches and structural systems. Based on constructed precedents, two structural systems are considered: a post-beam-panel system and a post-and-platform system. For these systems, a set of geometric parameters and variables are established to create a parametric design space, after which each geometry is subjected to structural analysis and structural design. The resulting design space contains significant diversity and can be used to assess the feasibility of the two considered structural systems for a range of geometries. The results show clear relationships between building height and the feasibility of using wood sections for lateral elements, as well as a positive relationship between the amount of structural material required and higher fire-resistance ratings, which can be interpreted in light of concern for embodied carbon.
