Abstract
This method is developed to determine the vibration controlled spans for wood joisted floors built with joists, subfloor, topping, and lateral reinforcements such as strong backs, straps, bridging or blocking. The floors may have a ceiling. The joists can be solid sawn lumbers, wood I-joists, or wood trusses. This method is also applicable to the floors built with the light-gauge steel joists with a wooden deck. The method accounts for subfloor, nail, or nail and glue connections between the joists and the subfloor, the topping, and the lateral reinforcements, and their effects on the vibration controlled spans of the floors. The effect of the ceiling is not taken into account since it was found to be insignificant (Hu 2005). The effect of the continuity of the joists over multiple spans was also found to be insignificant (Hu 2005), and is therefore, also not taken into account. This means that when we determine the vibration controlled spans for multiple span continued joists, we treat each span as a single span joisted floor and use this method to determine its vibration controlled span. This method is only applied to lightweight joisted floors that present fundamental natural frequencies larger than 9 Hz. The floor should be well-supported and built without construction defects as specified in the building code.

Abstract
The key objective of this study was to evaluate the surface burning characteristics (flame spread rating) of glued-laminated timber (glulam) decking in accordance with CAN/ULC S102 test method [1]. This is part of a test series aimed at evaluating the flame spread rating of mass timber components, such as cross-laminated timber (CLT) and structural composite lumber (SCL). More specifically, this study is solely focused on mass timber assemblies that are thick enough to be treated theoretically as semi-infinite solids (thermally thick solids) as opposed to thermally-thin, which is typical of traditional combustible finish products. The tested specimen in this series meets the provisions related to “heavy timber construction”, per paragraph 3.1.4.7 of Division B of the National Building Code of Canada.

Abstract
The main objective of this study is to evaluate the fire-protection F- and T-ratings of selected fire stops and sealing joints in cross-laminated timber assemblies, in accordance with CAN/ULC S115 test method, “Standard Method of Fire-Tests of Firestop System”. Recommendations are given in this report with respect to proper detailing to ensure that the tested closure devices, when used in mass timber plate construction, will perform as expected. It is noted that test data is to date limited, and further testing may result in revision of these recommendations.

Abstract
The key objective of this study is to conduct a preliminary evaluation of the structural fire-resistance of selected structural composite lumber (SCL), namely laminated veneer lumber (LVL) and laminated strand lumber (LSL), in accordance with CAN/ULC S101 “Standard Methods of Fire Endurance Tests of Building Construction and Materials”.
