Rapid growth of urban populations and associated environmental concerns created an opportunity for city planners and developers to consider sustainable building systems. A decision on the selection of the masstimber building, by different stakeholders, should consider economics, aesthetics, technology, regulations andpolitical factors. The political factors are indeed satisfied as the Canadian timber industry and NaturalResources Canada are backing design and construction of tall-timber buildings. One such initiative in BritishColumbia (BC) is Forrest Innovation Investment (FII) Wood First - 3 Year Strategy.? Canadian engineers anddesigners are at the forefront and are pushing the limit of tall-timber design. The 2019 CSA 086 and 2020 NBCincreased the height of cross-laminated timber (CLT) to 12 storeys.? With increase in building height, however,timber being lighter material, is subject to lateral loads from wind and earthquake (the focus of this proposal).Thus, there is an opportunity to propose an innovative building system and design principles.In line with the "Wood First Initiative" program of the government of BC, in the current proposal, it isenvisioned to develop a comprehensive design guideline for mid- to tall-mass-timber buildings (6-20 storeys).It is believed that the availability of design guideline would enhance the confidence of architects, structuralengineers, owners and contractors towards tall mass-timber buildings. Outcome of the proposed researchwould increase the volume of wood in buildings, which will support the forestry business in Canada.

城市人口和相关环境问题的快速增长为城市规划人员和开发商考虑了可持续建筑系统的机会。不同利益相关者对Masstimber建筑物选择的决定，应考虑经济学，美学，技术，法规和政治因素。由于加拿大木材行业和加拿大的自然要素正在支持高高的建筑物的设计和建造，因此政治因素确实得到了满足。不列颠哥伦比亚（BC）的一项此类倡议是Forrest Innovation Investment（FII）Wood第一至3年策略。加拿大的工程师和戴斯尼亚人处于最前沿，并正在推动高架设计的极限。 2019 CSA 086和2020 NBCINCRCRCRCRACHSCINACH跨层压木材（CLT）的高度至12层。然而，随着建筑高度的升高，木材的材料较轻，受风和地震的横向负载（该提案的重点）。因此，有机会提出一个创新的建筑系统和设计原理。与“木材第一倡议”计划一致，在当前的构建中，它可以制定一个综合的设计指南，以制定综合的设计，以制定6个较高的构建。人们认为，设计指南的可用性将增强建筑师，结构工具，所有者和承包商对高大群木建筑的信心。拟议的研究的结果将增加建筑物中木材的数量，这将支持加拿大的林业业务。
