This APA System Report provides prescriptive fire assemblies for fire protection of floors constructed with prefabricated wood I-joists that comply with 2021, 2018 and 2015 IRC Sections R502.1.2 & R302.13 and 2012 IRC Section R501.3.
The global construction industry is witnessing a surge in production volumes, particularly in residential construction. To address the growing demand for prefabricated and cost-effective housing, the proposition is to employ glued plywood panels as construction components for building floors and roofs. These panels, comprising a timber frame, plywood skins, and insulation, offer numerous advantages, including low weight and a high strength-to-weight ratio. The objective of this study was to diminish the material consumption of panels by comparing calculations using both the traditional engineering method and the finite element method within a software package. The methodology for calculating and designing glued plywood panels, when employing the engineering method, involves determining the geometric characteristics of the panel sections, accounting for variations in the elastic moduli of wood and plywood. In the numerical calculation, the design method of plate elements of the "ReGridQuad" type was chosen, with the assignment of the required plate thickness. The outcomes of all calculations revealed comparable stress and deflection patterns in structures. The values obtained from both calculations were found to be below the standard ones. Research in this domain underscores the significance of numerical calculation methods in enhancing the quality of glued plywood panels, rendering them more competitive in the building materials market.
In recent years, Cross-laminated Timber (CLT) has experienced exponential growth internationally, fostering substantial awareness and inter¬est in this renewable construction material. The increasing adoption of CLT in countries and regions of world is resulting in considerable manufacturing investment in engineered wood products more generally. Fabrication of solid timber structural systems using CLT panels requires product standards ensuring strength and stiffness characteristics of the base material in meeting rigorous performance requirements. Given that this nascent technology was only introduced within the last three decades, standards for manufacturing and design are still being developed. Indeed, multiple approaches to standards development have occurred in several regions of the world with little thought to harmonisation. This paper aims to review design standards from throughout the world for CLT and associated timber structures with recommendations towards future development of CLT standardization. For this purpose, an explanation of the general approach used by the following standards relating to CLT and timber codes is presented; Europe: EN-16351, North America: APA/PRG-320, Japan: JAS-3079, International Organization for Standardization (ISO) CLT standard: ISO 16696- 1, Africa: South Africa: SANS-1783/ SANS 10163/ SABS-0163, South America: Brazil: NBR-7190, Oceania: Australia: AS-1720.1, and Asia: China: GB-50005. The current versions of each standard are briefly outlined with the related standard background. For the development of standards in those countries that are yet to adopt a CLT standard, the potential of using other existing standards has been outlined as suggestions. The present review can be a useful resource for researchers, manufacturers, companies, and investors interested in further study of a worldwide harmonized CLT standard.
