The current life cycle assessment (LCA) methodology used in structural engineering does not consider hazards like fires within its scope. Various efforts have been made to identify research gaps that need to be filled in order to accomplish a Fire-LCA. This study presented research gaps from literature to experts to determine the research gap's impact, desirability, and probability of occurrence by the year 2030. The study provides insight into what researchers should prioritize to accomplish the proposed Fire-LCA methodology. In each round the experts were asked to evaluate and comment on the impact, desirability, and probability of occurrence by the year 2030 of each identified research gap. The results of the Delphi questionnaire identified high priority research gaps for the implementation of the proposed Fire-LCA methodology. The most prioritized research gap was statistical data that would describe the number and severity of fires, fire origin, and extent of fire spread in different types of building. The results of this study can guide researchers and funding agencies to prioritize research that will fill key gaps in knowledge that prevent the implementation of a Fire-LCA methodology for building structures. • Gaps in knowledge exist and prevent the implementation of a Fire-LCA methodology for buildings. • Statistical data and reporting of real building fires is needed for the implementation of a Fire-LCA methodology. • Experts across the world do not agree on research priorities to fill gaps in knowledge needed to implement a Fire-LCA.

• Evaluated effects of two brown rot fungi (Gloeophyllum trabeum and Rhodonia placenta) on performance of laterally loaded connections. • T-shaped connection assemblies modelling floor-to-wall connections in buildings were inoculated with fungi for up to 40 weeks. • Evaluated capacity, stiffness, energy dissipation, and ductility of connection assemblies through quasi-static cyclic connection tests. • Load carrying capacity and energy dissipating capacity were the most adversely affected of all the parameters evaluated. The effects of brown rot decay fungi on mechanical properties of CLT connection assemblies were investigated. CLT connections evaluated were assembled with code approved angle bracket connectors and modelled as floor-to-wall systems in mass timber buildings. Physical changes, mass loss and quasi-static cyclic tests were used to assess the performance of connection assemblies up to 40 weeks after fungal inoculation. Peak load, stiffness, energy dissipation and ductility of connections were characterized based on force–displacement data generated from the destructive test of connections. Assemblies experienced up to 57 % loss in load carrying capacity and 90 % loss in energy dissipating capacity of the connections after 40 weeks of fungal exposure. Connection stiffness was only slightly impacted over this period but wetting and redrying caused significant degradation of connection ductility. [ABSTRACT FROM AUTHOR]

• Tension tests of glued-in steel rods embedded in mass-ply panels are reported. • A two-step adhesive application process for glued-in steel rods is tested. • Monotonic and cyclic testing show no significant difference in tension capacity. • Elastic stiffness does not change with embedment depth under monotonic loads. • Further testing is required for conclusions on elastic stiffness under cyclic loads. The length of mass timber wall panels is a limiting factor in designing taller buildings. Splice designs are needed to maintain panel transportability while transferring shear and moment forces from higher floors to the foundation under lateral loading. One such splice design utilizes structural adhesive to glue threaded steel rods into the ends of wall panels being connected. This paper reports tests of the tension capacity of glued-in rods embedded in Mass Ply Panels (MPP). Twenty glued-in rods were tested under monotonic and cyclic protocols. Embedment depths ranged between 304.8 mm (12 in.) and 812.8 mm (32 in.). Load and displacement were measured during tests to report values per ISO 6891 and an international code council acceptance criteria document. Elastic stiffness, peak capacity, design capacity, and a predictive capacity equation were determined. Results showed a similar stiffness for all embedment depths and a negligible difference between peak capacities from monotonic and cyclic testing. While the data reported is only directly applicable for analysis of the specific MPP and epoxy combination used in the test program, the methodology herein can be utilized for future testing of timber-adhesive glued-in rods.
