Summary
This monitoring study aims to generate field performance data from a highly energy efficient building in the west coast climate as part of FPInnovations’ efforts to assist the building sector in developing durable and energy efficient wood-based buildings. A six-storey mixed-use building, with five storeys of wood-frame residential construction on top of concrete commercial space was completed in early 2018 in the City of Vancouver. It was designed to meet the Passive House standard. The instrumentation aimed to gather field data related to the indoor environment, building envelope moisture performance, and vertical movement to address the most critical concerns among practitioners for such buildings.

Summary
Timber-concrete-composite (TCC) floors are a successful example of hybrid structural components. TCC are composed of timber and concrete layers connected by a shear connector and are commonly used in practical civil engineering applications. The connection of the two components is usually achieved with mechanical fasteners where relative slip cannot be prevented and the connection cannot be considered rigid. More recently, an adhesively bonded TCC system has been proposed, and has been shown to perform predictably under static short-term loading. One of the main considerations when designing TCC floors is their long-term performance. In the research presented herein, two adhesively bonded TCC beams were exposed to serviceability loads for approximately 4.5 years. During this time the environmental conditions and the deflections were monitored. After having been loaded for 4.5 years, the beams were tested to failure, resulting in findings that long-term loading caused no degradation of the adhesive bond. This research provides input data to develop design guidance for adhesively bonded TCC under long-term loading.

Summary
Timber-concrete-composite (TCC) floors, composed of timber and concrete layers connected by a shear connector are a successful example of hybrid structural components and are commonly used in practical applications.The connection of the two components is usually achieved with mechanical fasteners where relative slip cannot be prevented and the connection cannot be considered rigid. The growing availability of panel-type engineered wood products (EWPs) offers versatility in terms of architectural expression and structural and building physics performance. Preceding research determined the properties for a range of TCC connector systems in several EWPs using full-scale short-term bending tests. In the research presented herein, nine TCC floor segments (one specimens of each previously investigated configuration) were exposed to serviceability loads for approximately 2.5 years. During this time, the environmental conditions and the deflections of each floor were monitored. After having been long-term loaded, the floor segments were tested to failure. The results show an increase of deflection over time but neither bending stiffness,load-carrying capacity nor vibration performance were impacted by the long-term loading. This research provides input data to develop design guidance for TCC floors.
