中文摘要
大质量木材是一种工程木材材料(如交叉层压木材、平行层压木材、胶合层压木材等),可作为中高层建筑的主要结构和建筑围护结构,被广泛认为比混凝土和钢材更具可持续性。虽然自21世纪初以来,大块木材已经在北美市场上销售,但对大块木材的适用性和耐久性的研究还存在空白,特别是对湿热性能及其与水分循环、蠕变和差移的关系的研究。为了研究大量木材的湿热特性和预测耐久性的能力,瑞尔森大学与多伦多和地区保护局(TRCA)合作,为加拿大各地的设计师、消费者、制造商和政府填补了这一空白。该研究将包括在TRCA位于安大略省多伦多的新行政办公大楼建造和使用期间,将实验室实验与持续监测/测量和现场测试联系起来。本研究的主要目标是创建一个数值工具,以促进对大型木结构建筑耐久性的理解和预测。两个次要目标是:(1)加强与大型木材传感器设计和监测相关的最新研究水平;(2)增加对大型木结构建筑中水分循环和尺寸变化耦合性能的理解。该研究项目将通过各种传统学术和非传统传播渠道,为加拿大制造商、设计师、顾问、政府和公众提供具有预测能力的大型稳健数据集。此外,该项目的知识转移将支持中小型住宅建筑市场(即公寓和公寓)中大量木结构建筑的发展,通过增加舒适性,减少能源使用和碳足迹,使更多的加拿大人受益。#(cr)#(f) bois massiest un matmatsiriau de bois d' ingsamnierie(例如,bois lamellemacry - crois<e:1>、bois lamellemacion -平行<e:1>、bois lamellemacry - coll<s:1>等)qui peut être utilis<e:1> comme structure principale et enveloppe du bestiment pour les immeubles de moyenne and grande hauteur。batiments et的最大尺寸考虑到<s:1> <s:1> <s:1>运输运输系统和耐用的<s:1> <s:1>运输运输系统和<s:1>运输运输系统。从2000年开始,将会有一种新的研究方法,即研究和服务的能力,以及研究和服务的能力,特别是研究和服务的能力,以及研究和服务的能力,特别是研究和服务的能力,研究和服务的能力,特别是研究和服务的能力,研究和服务的能力,研究和循环的能力,研究和流动的能力,研究和流动的能力。为研究人员提供了一种新的方法,使其能够在加拿大境内的其他地方使用。例如,为研究人员提供了一种新的方法,使其能够在加拿大境内的其他地方使用。综合研究中心、实验室实验中心、监测/措施中心、现场测试中心、施工中心和新行政中心、加拿大安大略省多伦多。我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标是,我的目标。二级目标为:(1)<s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1> <s:1>混合材料材料(<s:1>混合材料材料)- <s:1>混合材料材料(<s:1>混合材料材料)- <s:1>混合材料材料(<s:1>混合材料材料)- <s:1>混合材料材料(<s:1>混合材料材料)的变化。加拿大的研究项目包括:加拿大的工业、工业、工业、工业、工业、工业、工业、工业、工业、工业、工业、工业、工业、工业、工业和工业
英文摘要
Mass timber is an engineered wood material (e.g. cross-laminated timber, parallel strand timber, glue laminated timber, etc) that can be used as the primary structure and building envelope for mid to high-risebuildings and is widely considered to be more sustainable than concrete and steel. Although mass timber has been available in the North American market since the early 2000s, there is a gap of research on mass timber serviceability and durability, particularly hygrothermal performance and its relationship to moisture cycling, creep and differential movement. To research the hygrothermal properties of mass timber and the ability to predict durability, Ryerson University has partnered with the Toronto & Region Conservation Authority (TRCA) to fill this gap for designers, consumers, manufacturers, and governments across Canada. The research will comprise linking laboratory experimentation with continued monitoring/measurement and in-situ testing during construction and occupancy of the TRCA's new administrative office building situated in Toronto, ON. The prime objective of this research is to create a numerical tool to foster understanding and prediction of the durability of mass timber buildings. Two secondary objectives are: (1) to enhance current state of the art research associated with mass timber sensor design and monitoring, and (2) to increase the understanding of the coupled performance of moisture cycling and dimensional changes in mass timber buildings.This research project will provide to Canada a large, robust data set, with predictive capability, to Canadianmanufacturers, designers, consultants, governments, and the public using various traditional academic andnon-traditional dissemination outlets. Additionally, knowledge transfer from this project to support the growth of mass timber building in the small to medium residential building market (i.e. condominiums andapartments) will benefit a larger portion of Canadians through increased comfort, and decreased energy use and carbon footprint.#(cr)#(lf)Le bois massif est un matériau de bois d'ingénierie (par exemple, le bois lamellé-croisé, le bois à torons parallèles, le bois lamellé-collé, etc.) qui peut être utilisé comme structure principale et enveloppe du bâtiment pour les immeubles de moyenne et grande hauteur.bâtiments et est largement considéré comme plus durable que le béton et l'acier. Bien que le bois massif soit disponible sur le marché nord-américain depuis le début des années 2000, il existe un manque de recherche sur l'aptitude au service et la durabilité du bois massif, en particulier la performance hygrothermique et sa relation avec le cycle d'humidité, le fluage et le mouvement différentiel. Pour rechercher les propriétés hygrothermiques du bois massif et la capacité de prédire la durabilité, l'Université Ryerson s'est associée à la Toronto & Region Conservation Authority (TRCA) pour combler cette lacune pour les concepteurs, les consommateurs, les fabricants et les gouvernements partout au Canada. La recherche comprendra le lien entre l'expérimentation en laboratoire et la surveillance / mesure continue et les tests in situ pendant la construction et l'occupation du nouvel immeuble administratif de la TRCA situé à Toronto, en Ontario. L'objectif premier de cette recherche est de créer un outil numérique pour favoriser la compréhension et la prévision de la durabilité des bâtiments en bois massif. Deux objectifs secondaires sont: (1) améliorer la recherche actuelle de pointe associée à la conception et à la surveillance des capteurs de bois massif, et (2) accroître la compréhension de la performance couplée du cycle d'humidité et des changements dimensionnels dans les bâtiments en bois massif.Ce projet de recherche fournira au Canada un vaste ensemble de données robustes, avec une capacité prédictive, aux Canadiens fabricants, designers, consultants, gouvernements et le public utilisant divers universitaires et moyens de diffusion non traditi
