Today’s building codes coupled with advances in wood science and building technology have expanded the options for wood construction. Building codes recognize wood’s safety and structural performance capabilities and allow its use in a broad range of applications, from the light-duty repetitive framing common in small structures to the larger and heavier framing systems used to build larger and taller buildings—including highrises, 竞技场和工厂.
The 2021 IBC includes three new construction types—Type IV-A, IV-B and IV-C—which allow the use of mass timber or noncombustible materials in buildings up to 18, 12层和9层(分别). 在以前版本的代码下, wood buildings can usually be a maximum of five or six stories depending on the occupancy group. The term “tall timber” is associated with buildings that exceed the limits of previous codes for number of stories, 高度和某些情况下的面积.
Whether you’re working on your first mass timber project or your 10th, we have resources that can make the process more efficient. Check out our inventories of fire resistance-tested and acoustically-tested assemblies, or browse our 计算机辅助设计/Revit tool for connection details. Gain insight from papers focused on code-related topics—such as fire design of mass timber members, 隐蔽空间或井壁要求. 参加我们的工作坊, webinars and other events to hear firsthand from experienced mass timber professionals.
To simplify code analysis for Type III and V mixed-use buildings, 这篇论文提供了逻辑, 设计关键方面的代码兼容步骤, such as allowable building size and fire separation.
查看资源高度和面积(H&A) Calculator app for iPhone and Android is a joint effort of WoodWorks and the American Wood Council. It provides users with an app-based approach to calculating maximum heights and areas for buildings of various occupancies and fire protection based on 2006 to 2015 editions of the International Building Code (IBC). Input a potential building’s geometry, site conditions (e.g., 开放的正面), 建筑类型, 和入住率, and allowable heights and areas can be determined.
This calculator is not meant to be a replacement for the IBC and does not encompass all of its design options. The IBC should always be consulted for specific requirements related to designs and site conditions. 了解更多
