Performance-Based Design of Tall Mass Timber Buildings Under Earthquake and Fire Loads

城市人口的快速增长和相关的环境问题为城市规划者和开发商创造了考虑可持续建筑系统的机会。不同的利益相关者在决定选择按摩师建筑时，应该考虑经济、美学、技术、法规和政治因素。政治因素确实令人满意，因为加拿大木材行业和加拿大自然资源公司支持设计和建造高木建筑。不列颠哥伦比亚省(BC)的一个这样的倡议是福雷斯特创新投资(FII)木材第一个3年战略。加拿大的工程师和设计师走在了前列，正在突破高木设计的极限。2019年CSA 086和2020 NBC将交叉层合木材(CLT)的高度增加到12层。然而，随着建筑高度的增加，木材作为更轻的材料，受到风和地震的横向荷载(本提案的重点)。因此，有机会提出一种创新的建筑体系和设计原则。根据不列颠哥伦比亚省政府的“木材优先”计划，在本提案中，设想制定一套全面的中高层质量木材建筑(6-20层)的设计准则。相信设计准则的可获得性将增强建筑师、结构工程师、业主和承包商对高层质量木材建筑的信心。拟议的研究结果将增加建筑物中的木材体积，这将支持加拿大的林业业务。

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.
