Summary
A survey was conducted under the "Renessaince in Wood Construction" project that was funded by Natural Resources Canada (NRCan) under the Transformative Technologies Program to see information about numerical modelling on mass timber buildings. A questionnaire was sent to designers and researchers covering different performance attributes. The compiled information includes the available software packages and resources of empirical equations that are used by the designers and researchers for predicting the structural, fire, acoustic, and building envelope (energy and durability) performance of mass timber buildings, and the challenges that they are facing in using those tools. This report summarizes the input obtained from practicing designers and researchers who responded to this survey.

Summary
Long-span timber-concrete composite (TCC) floor systems have the potential to address the design challenges for conventional wooden floors in residential multi-storey timber frame buildings. The aim of this paper is to develop a design approach for long-span timber-concrete composite floor system of 6–9 m. A framework based on value-driven design approach has been developed for integration of results from graphical multi-objective optimisation, spreadsheet-based analysis, structural static and dynamic finite element analysis, and multi-criteria decision making. To verify the developed framework, a residential five-storey timber frame building as a case study has been studied. Optimal design includes optimised thickness of the concrete and optimised smeared stiffness of connectors for three different comfort classes A to C in descending order. TCC floor with span length 7.3 [m] belonging to comfort class A and TCC floor with span length 9.0 [m] belonging to comfort class C has been chosen as optimal solutions. The results indicate that proposed and innovative design approach is a promising tool for developers, architects and structural engineers when designing optimal long-span timber-concrete composite floor system.
