“…A relevant parameter is the ratio ( a/d ) that can modify the shear failure mode in reinforced concrete beams, as highlighted by Nakamura et al [29]. Plasencia et al [30] state that the failure of beams with ratio ( a / d<2 ) was due to the rupture of the compression strut. This behavior was also observed in the post-fire shear capacity based on the experimental data presented, where the residual strength was influenced by the distance of the load applied to the support (a), effective height (d) and free span of the beam (L).…”

A procedure to estimate the residual bending moment and the shear load capacity after fire in reinforced concrete beams was evaluated. The calculation method is based on the 500ºC Isotherm Method, adopting the reduction coefficients proposed by Van Coile et al. (2014) for the steel yield strength. The proposed method validation was done from experimental results of 62 reinforced concrete beams available in the literature. It was possible to observe a good approximation of the analytical method with the experimental data. For the bending moment an average ratio M r ana / M r exp of 1.04 and standard deviation of 0.15 was found. For the shear force an average ratio V r ana / V r exp of 0.85 and standard deviation of 0.23 was found.
