Abstract
There is a need to demonstrate how novel timber-concrete composite floors can span long distances and be a practical alternative to other traditional structural systems. Better understanding of the fire behaviour of these hybrid systems is essential. To achieve this, the fire-resistance of a timber-concrete composite floor assembly, using BC wood products, will be evaluated in accordance with CAN/ULC-S101 [2]. A 2 hr fire resistance rating will be targeted, as this is the current requirement in high-rise buildings for floor separations between occupancies. The structural behaviour of this type of system will also be assessed from conducting pull-out tests of the shear connectors. In conjunction with previous test data, the results of this test will be used to develop an analytical model to assess the structural and fire-resistance of timber-concrete composite floors. 301010618

Abstract
The existing softwood kilns are vastly oversized and ill equipped to dry the volume of hardwood lumber identified for the study. A dehumidification kiln with a twenty thousand board foot (20 Mbf) capacity would be the most cost effective kiln drying technology. It would be well matched to the annual volume to be dried and does not require specialized skills to operate. Such an operation would require a price differential between green and dry lumber of approximately $120 per Mbf to be viable. Within the study area, there exists a small volume of veneer quality hardwood resource. A longitudinal veneer slicing system would be well suited to process the volume available. Such a system would process green lumber to produce high quality, sliced face veneer. White birch, however, has little figure or grain when sliced and hence, little advantage over rotary cut birch veneer. To be viable, markets for the sliced veneer would have to be developed at the current market price for rotary cut face veneer. This should not be too difficult as the volume is relatively small. The fact that suitable technology exists for the kiln drying and veneering operations is encouraging. If markets in these two areas can be developed, it is recommended that consideration be given to the concept of a wood products industrial park. Initially, the core enterprise of the park would be a lumber concentration yard with dry kilns and possibly dressing facilities. It could be expanded at a later date to include a small sawmill and the veneer operation. As markets develop, consideration could be given to other complementary industries which build on the expertise and resources of the industrial park. This concept is further detailed in the report.
