Abstract
The objective of this study is to evaluate the fire behavior of CLT manufactured with different types of SCL or lumber boards, namely with laminated veneer lumber (LVL), laminated strand lumber (LSL) and Trembling Aspen. The fire test data is also compared to those of CLT manufactured in accordance with ANSI/APA PRG-320 using solid-sawn lumber grades. More specifically, the study aims at evaluating the charring rates of this new generation of CLT panels as well as the impact of their manufacturing parameters.

Abstract
The design of wood-frame structural systems to withstand exposure to fire depends on knowledge of the fire endurance (time-to-failure) of the wood members used in the system. In fires, wood looses part of its load-carrying capacity due to charring and part due to strength degradation. This thesis examines the reduction in compression strength experienced by dimension lumber when exposed to elevated temperatures. A program of experimental testing of nominal 2×4 Machine Stress Rated (MSR) lodgepole pine lumber concentrically loaded in compression and exposed to elevated temperature was undertaken by Forintek Canada Corp., Canada's wood products research institute. A computer program entitled HTExposure was written to simulate the experimental time-to-failure data gathered in Forintek's testing program. This computer program combines a modification of an existing heat-transfer model with various published compression-strength reduction models. This was done in order to determine which of those strength-reduction models could predict times-to-failure comparable to the observed values. As well, a new compression-strength reduction model was proposed. When predicted results were compared to the observed data, it was determined that the computer program predicted results closest to those observed when using the new compression-strength reduction model proposed in this study.
