Mass Timber Construction Journal 2022-09-23T09:32:24+10:00 Paul Kremer Open Journal Systems <p>The Mass Timber Construction Journal is a peer-reviewed international online journal, dedicated to high quality research in Mass Timber Construction (MTC). The journal was created to fill an identified gap in the research publishing market. The editors found it difficult to publish MTC research in other journal publications due to a lack of concentrated peer-reviewers, editorial staff and researchers who are the leaders in the MTC field.</p> Overview of Cross-Laminated Timber (CLT) and Timber Structure Standards Across the World 2022-05-28T20:30:30+10:00 Shaghayegh Kurzinski Paul Crovella Paul Kremer <p class="p1">&nbsp;<em>In recent years, Cross-laminated Timber (CLT) has experienced exponential growth internationally, fostering substantial awareness and inter┬Čest 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.<span class="Apple-converted-space">&nbsp;</span></em></p> 2022-05-28T00:00:00+10:00 ##submission.copyrightStatement## Shear strength testing of adhesive bonds in laminated elements made from palm trees 2022-09-23T09:32:24+10:00 Ammar Ilyan Gharbi Karol Sikora <p>With the constant increase in world population, the need for further infrastructure development has become more important than ever. To accommodate such growth, vast structures are built which utilize concrete and steel, thus leading to the increase of green-house gasses emission. The world therefore, has attempted to find an alternative construction material. One possible alternative is timber which has already demonstrated its capacity in the various structures built around the world. However, there are regions without trees. In the Middle East only palm trees are abundant. This research focuses on studying the bonding shear strength of laminated palm leaf elements. The adhesives used in this research were Polyurethane (PUR), Diallyl Phthalate (DAP) and Diallyl Phthalate (DAP cement) and were subjected to three different clamping pressures; 0.6MPa, 0.8MPa, and 1.0MPa to obtain the optimum bonding parameters. This research revealed that DAP adhesive produced the highest shear strength values of all the three adhesives as the clamping pressure increased, however, PUR adhesive shear strength values demonstrated the highest consistency. DAP cement adhesive showed the least consistency.</p> 2022-09-23T00:00:00+10:00 ##submission.copyrightStatement##
