Residual behavior of steel rebars and R/C sections after a fire

Towards a reliability‐based post‐fire assessment method for concrete slabs incorporating information from inspection

“…Furthermore, for hot-rolled rebars, a distinction should be made between the quenched and self-tempered (QST) reinforcement popular in Europe and the carbon steel reinforcement often used in the United States. According to experiments by Felicetti et al (2009) [11], QST reinforcement exhibits less strength recovery. These results reported by Felicetti et al have been adopted in fib Bulletin 46 [1].…”

“…Values for k fy,res found in the literature are summarized in Table 3, as well as the stochastic model (for QST reinforcement) proposed in this article. As limit- ed test results are available, assumptions with respect to the standard deviation of the reinforcement residual strength have been made, based on [11] and [14]. In the case of carbon steel reinforcement, the stochastic model of Table 3 However, these values are based on a small number of available test results.…”

“…Some studies have even investigated the reliability of structural elements during fire exposure [6][7][8][9], ultimately allowing, for example, optimization of the design by balancing upfront investments in safety with a reduced probability of failure during the lifetime of the structure [10]. However, few studies focus on the residual structural capacity after fire exposure (see [11,12], for example), and to the best of the authors' knowledge, no userfriendly method for assessing the maximum service load after fire exposure has been proposed. As exposure to elevated temperatures may result in permanent damage to concrete and reinforcement [1,[13][14][15], the maximum service load may be significantly reduced after fire exposure.…”
