Resilient-Timber Building Incorporating Energy Dissipators: Analytical and Experimental Tests

城市人口的快速增长和相关的环境问题正在向城市规划者和开发商提出挑战，要求他们考虑可持续的建筑系统。木材是这样一种可持续的材料，但2015年加拿大国家建筑规范(NBC)将杆架结构的高度限制在6层。然而，随着最近大规模工程交叉层合板(CLT)和胶合板的引入，中高层木结构建筑成为可行的选择。因此，2020年全国广播公司将把CLT等大宗木材的限制提高到12层。 在这项提案中，考虑了一种弹性木结构建筑，用于中层(6至8层)和高层(10至20层)建筑，使用创新的消能器和结构系统。该提案的第一部分将通过引入具有重新定位能力的CLT墙的耦合消能轻框建筑来推动中层建筑的限制。由于目前的设计规范没有涵盖这种类型的系统，本提案将制定基于性能的设计指南。

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.
