Abstract
The objective of this work is to generate fire resistance data for NLT assemblies to address significant gaps in technical knowledge. This research will support designers and builders in the use of mass timber assemblies in larger and taller buildings, as well as provide scientific justification for Authorities Having Jurisdiction (AHJ) to review and accept this construction method. The intent is to demonstrate that NLT construction can meet or exceed NBCC fire safety requirements for use in buildings of mass timber construction. The data could be used towards the inclusion of an NLT fire resistance calculation methodology into Annex B of CSA O86 – Engineering Design for Wood [4], which currently addresses only glue-laminated timber (GLT), structural composite lumber (SCL) and cross-laminated timber (CLT).

Abstract
The objective of this work is to generate fire performance data for NLT assemblies to address gaps in technical knowledge. This project aims to study how the size of gaps between NLT boards might affect charring of an assembly and its overall fire performance. This research will support designers and builders in the use of mass timber assemblies in larger and taller buildings, by ensuring fire safe designs.

Abstract
The objective of this project is to establish fundamental fire performance data for the design and specification of NLT assemblies; this project specially addresses determining FSRs for NLT. The goal of this project is to confirm that NLT, when used as a mass timber element, has a lower FSR than standard thickness SPF boards when tested individually and flatwise. The project also considers how the surface profiles, design details, and the direction of an assembly might influence flame spread. This includes the evaluation of typical architectural features, such as a ‘fluted’ profile. Having this technical information will support project approvals for the use of NLT elements in larger and taller wood buildings, as well as provide scientific justification for Authorities Having Jurisdiction (AHJ) to review and accept this construction method. This research will provide the evidence for designers to demonstrate their design have met or exceeded fire safety requirements. Ultimately the intent is to expand the adoption of manufactured solid timber construction for larger and taller buildings, as well as for non-traditional wood markets (such as institutional or commercial buildings). Other aspects of this project (in separate reports) include evaluating fire resistance of NLT, and assessing how NLT charring rates might be affected by gaps between boards.

Abstract
Nail-Laminated Timber (NLT) and box beam are efficient and economical engineered wood products. Although NLT has been used in North America for more than a century, only in recent years it has gained renewed interests as they have been seen as the most economical panel products used in mass timber buildings. Box beams, on the other hand, are lightweight and generally possess higher strength and stiffness than comparable-sized solid timber and are more efficient than solid timber for large spans and loads. In this report, existing design provisions and their limitations for the design and construction of NLT and box beam in Canadian standards are reviewed. For NLT, there is a general lack of information related to manufacturing, design and construction to ensure consistent manufacturing and installation practices. Therefore, it is difficult to research and document with confidence the full range of performance that can be achieved with NLT. It is therefore recommended that a North American product standard and design information on structural performance, floor vibration, fire resistance, acoustic performance, and construction risk mitigation measures (e.g. moisture and fire) be developed. In CSA O86, design methods are limited to box beams with flanges and webs bonded with glue. As the flanges and webs of a box beam can be assembled by either glue or mechanical fasteners, it is recommended that design provisions for box beam with mechanical joints be also developed. With the information in Eurocode 5 and relevant supporting research papers, it is ready to be implemented.

Abstract
Glulam rivets (or Griplam nails) are high strength steel nails originally developed in Canada to connect glued-laminated timbers (glulam) by means of pre-drilled steel side plates. Glulam rivets are considered one of the most efficient connectors in wood construction mainly because of their high load carrying capacity. However, CSA-O86.1, Code for Engineering Design in Wood does not provide design values for glulam rivet connections with sawn timber. The Fastenings Subcommittee of the CSA Technical Committee (TC) on Engineering Design in Wood has identified a need to extend the use of glulam rivet connections to sawn timber with appropriate service condition factors, and to investigate the effect of plate thickness on joint capacity. This project involving testing and analysis of sawn timber glulam rivet connections was initiated in the 1990/91 fiscal year. Since then, progress has been communicated to members of the Glulam Rivet Task Group of the TC on Engineering Design in Wood. Lateral resistance, rivet withdrawal, rivet embedment, and rivet bending tests were performed. Lateral load resistance test data were analyzed to investigate the effect of species, loading type and direction, environmental conditions, density, waiting period between assembly and test, pre-drilling, and plate thickness. Withdrawal load test data were analysed to investigate the effect of species, environmental conditions, density and waiting period. Recommendations for code implementation were made. Rivet embedment and rivet bending test data were used as input parameters with the European Yield Theory to predict the lateral resistance in rivet yielding failure mode.

Abstract
Glulam rivets (or Griplam nails) are high strength steel nails developed originally (in Canada) to connect glued-laminated timbers (glulam) by means of pre-drilled steel side plates. Glulam rivets are considered one of the most efficient connectors in wood construction mainly because of their high load carrying capacity. However, CSA-O86.1, Code for Engineering Design in Wood does not provide design values for glulam rivet connections with sawn timber. The Fastenings Subcommittee of the CSA Technical Committee (TC) on Engineering Design in Wood has identified a need to extend the use of glulam rivet connections to sawn timber with appropriate service condition factors, and to investigate the effect of plate thickness on joint capacity. This project involving testing and analysis of sawn timber glulam rivet connections was initiated in the 1990/91 fiscal year. Since then, progress has been communicated with members of the Glulam Rivet Task Group of the TC on Engineering Design in Wood. In the 1992/93 fiscal year, a) The testing part of the project was completed. Lateral load resistance and rivet withdrawal test data were analyzed to investigate the effect of species, loading type and direction, environmental conditions, density, waiting period between assembly and test, pre-drilling, and plate thickness; b) A revised draft of glulam rivet design section of CSA Standard O86.1 was prepared and distributed to Glulam Rivet Task Group members, and discussed in the November 1992 meeting of the Fastenings Subcommittee. Revisions will be finalized in the 1993/94 fiscal year; and c) Based on an invitation by the program committee of the International Workshop on Wood Connectors (held in Las Vegas, November 1992), a technical paper entitled "Canada overview - glulam rivets" was presented. In the 1993/94 fiscal year, data analysis will be completed, design values and factors will be proposed and discussed with members of the Glulam Rivet Task Group and then submitted to the Fasteners Subcommittee of CSA TC on Engineering Design in Wood for code implementation.

Abstract
The Fastenings Subcommittee of the CSA Technical Committee (TC) on Engineering Design in Wood has identified a need to extend the use of glulam rivet connections to sawn timber with appropriate service condition factors, and to investigate the effect of plate thickness on joint capacity. A total of 640 lateral resistance tests on glulam rivet/sawn timber specimens were performed. The load carrying capacity of glulam rivet/sawn timber connections was determined in rivet yielding mode. Preliminary data analysis on the effect of species, loading type and direction, environmental conditions, density, waiting period between assembly and test, pre-drilling, and plate thickness on the load carrying capacity was performed. In the 1992/93 fiscal year, the remaining testing will be completed, findings will be discussed with the members of the Glulam Rivet Task Group, and then submitted to the Fasteners Subcommittee of CSA TC on Engineering Design in Wood.
