“…As shown in Figure 4, this property increases steadily with temperature until around 700 or 800C (for siliceous or calcareous aggregates, respectively) after which it plateaus and remains constant; this is due to chemical changes in the constituent materials at these temperatures [25].…”

Corrosion of carbon steel reinforcing bar can lead to deterioration of concrete structures, especially in regions where road salt is heavily used or in areas close to sea water. Although stainless steel reinforcing bar costs more than carbon steel, its selective use for high risk elements is cost-effective when the whole life costs of the structure are taken into account. Considerations for specifying stainless steel reinforcing bars and a review of applications are presented herein. Attention is then given to the elevated temperature properties of stainless steel reinforcing bars, which are needed for structural fire design, but have been unexplored to date. A programme of isothermal and anisothermal tensile tests on four types of stainless steel reinforcing bar is described: 1.4307 (304L), 1.4311 (304LN), 1.4162 (LDX 2101  ) and 1.4362 (2304). Bars of diameter 12 mm and 16 mm were studied, plain round and ribbed. Reduction factors were calculated for the key strength, stiffness and ductility properties and compared to equivalent factors for stainless steel plate and strip, as well as those for carbon steel reinforcement. The test results demonstrate that the reduction factors for 0.2% proof strength, strength at 2% strain and ultimate strength derived for stainless steel plate and strip can also be applied to stainless steel reinforcing bar. Revised reduction factors for ultimate strain and fracture strain at elevated temperatures have been proposed. The ability of two-stage Ramberg-Osgood expressions to capture accurately the stress-strain response of stainless steel reinforcement at both room temperature and elevated temperatures is also demonstrated.

“…These systems again require a detailed evacuation strategy and method of communication to occupants as to their required egress destination. Several case studies demonstrate the use of some of the listed strategies, including the Marina Bay Sands in Singapore (Lovatt and Wong 2012), the Shenzhen Stock Exchange in China (Chen et al 2014) and a UK Retail and Leisure Complex (Wang et al 2013). .…”

“…A structural analysis of the floor at elevated temperature was performed for each design fire to determine maximum slab deflections. The stability of the floor relied on tensile membrane action, and the acceptance criteria was a deflection limit of L/20 (Wang et al 2013). Several options for connection design were discussed including designing for the actual forces from the analysis, providing sufficient ductility, and ensuring secondary beams are supported after failure of the connections (Wang et al 2013).…”

The goal of fire safety engineering (FSE) is to design a strategy that meets human safety and property protection goals with an optimized solution. In comparison to international practice, Canada could be considered highly underdeveloped in a technical perspective of performance versus prescription. In Canada, FSE is a subdivision within civil and mechanical engineering, rather than treated as a profession in and of itself. With a requirement for more complex infrastructure to meet Canadian societal needs, there is stimulus that is fostering a demand to create professionals educated with FSE skill sets. This literary study therefore aims to present a state-of-the-art review of the design practice of FSE in Canada and abroad with explicit focus on performance-based fire design for the Canadian practitioner who seeks to develop their expertise in this subject.

Fire safety considerations have an impact on the design of almost all structures, ranging from small residential structures to high-rise buildings. One important aspect of building fire safety is structural-fire safety, with the goal of preventing or delaying collapse of structures during severe fires. Structural-fire safety is of particular importance for steel structures, because of the high thermal conductivity of steel. Structural-fire safety design is most often accomplished using nonengineered prescriptive approaches. However, there is increasing interest in engineered structural-fire safety design for potential advantages in safety, economy and design flexibility. This paper provides an overview of engineered structuralfire safety design for steel buildings, and discusses some of the challenges in this field.
