Rapid growth of urban populations and associated environmental concerns are challenging city planners and developers to consider sustainable building systems. Timber is such a sustainable material, but the 2015 National Building Code Canada (NBC) limits height of stick frame construction to 6 storeys. With recent introduction of large-scale engineered cross-laminated timber (CLT) panels and glulam timber, however, mid- and high-rise timber buildings became viable option. Consequently, the 2020 NBC will push the limit of mass timber, such as CLT, to 12 storeys. In this proposal, a resilient timber buildings for mid-rise (6- to 8-storey) and high-rise (10- to 20-storey) buildings using innovative energy dissipators and structural systems is considered. The first part of the proposal will push the mid-rise building limits by introducing coupled energy-dissipator light frame buildings with CLT wall that has recentering capability. As this type of system is not covered in the current design code, this proposal will develop performance-based design guideline.

城市人口和相关环境问题的快速增长是城市规划人员和开发商考虑可持续建筑系统的挑战。木材是一种可持续的材料，但2015年加拿大国家建筑法规（NBC）将棒框架建设的高度限制为6层。然而，随着大型工程跨层压木材（CLT）和Glulam Timber的引入，中高层木材的建筑成为可行的选择。因此，2020年NBC将将大规模木材的极限（例如CLT）推到12层。 在此提案中，考虑了使用创新能量消散器和结构性系统的中层（6至8层）和高层（10至20层）建筑物的弹性木材建筑。该提案的第一部分将通过带有近期功能的CLT墙引入耦合的能量分流器轻型框架建筑物来推动中层建筑限制。由于当前的设计代码未涵盖这种类型的系统，因此该提案将制定基于绩效的设计指南。
