Mass Timber
Description
The most comprehensive reference on building with mass timber, extensively covering its sustainability, materials, building conceptualization, structural design and construction processes
Mass Timber: Materials, Design, and Construction is a one-stop resource book for mass timber construction with thorough textual descriptions, engaging images, many concept drawings, and discussion of state-of-the-art construction practices. The book draws from a large pool of images from the every-day to cutting-edge mass timber construction projects and includes extensive details of recently constructed buildings.
Written by a renowned team of experts with over three decades of professional, research, and teaching experience, Mass Timber: Materials, Design, and Construction includes information on:
- Sustainability and climate-related benefits of mass timber
- Historical applications and products leading up to the current day
- Mass timber materials such as cross-laminated timber (CLT), glue-laminated timber (glulam), nail- and dowel-laminated timber (NLT and DLT), structural composite lumber (PSL and LVL) and the many fastener types used with such materials
- Resiliency considerations for wood such as decay, fire, weathering, and its protection during construction
- Building conceptualization, covering building codes and systems as well as preliminary design considerations
- Structural design principles for gravity and lateral loads as well as connection design and detailing
- Construction processes, covering procurement, scheduling and lead time, estimating, risk management, on-site storage, and hoisting
Mass Timber: Materials, Design, and Construction is an excellent classroom or studio companion for students in architecture, engineering, and construction, and a valuable desk reference for any professional in these and related fields.
