As shown in Fig. Constr. Further information on the elasticity of concrete is included in our Modulus of Elasticity of Concrete post. These measurements are expressed as MR (Modules of Rupture). In addition, CNN achieved about 28% lower residual error fluctuation than SVR. 11, and the correlation between input parameters and the CS of SFRC shown in Figs. In Empirical Inference: Festschrift in Honor of Vladimir N. Vapnik 3752 (2013). 2(2), 4964 (2018). 27, 102278 (2021). 16, e01046 (2022). It was observed that among the concrete mixture properties, W/C ratio, fly-ash, and SP had the most significant effect on the CS of SFRC (W/C ratio was the most effective parameter). As there is a correlation between the compressive and flexural strength of concrete and a correlation between compressive strength and the modulus of elasticity of the concrete, there must also be a reasonably accurate correlation between flexural strength and elasticity. c - specified compressive strength of concrete [psi]. Regarding Fig. These cross-sectional forms included V-stiffeners in the web compression zone at 1/3 height near the compressed flange and no V-stiffeners on the flange . Invalid Email Address.

Article Buy now for only 5. Karahan et al.58 implemented ANN with the LevenbergMarquardt variant as the backpropagation learning algorithm and reported that ANN predicted the CS of SFRC accurately (R2=0.96). Appl. Scientific Reports The implemented procedure was repeated for other parameters as well, considering the three best-performed algorithms, which are SVR, XGB, and ANN.

Fluctuations of errors (Actual CSpredicted CS) for different algorithms. Based on the results obtained from the implementation of SVR in predicting the CS of SFRC and outcomes from previous studies in using the SVR to predict the CS of NC and SFRC, it was concluded that in some research, SVR demonstrated acceptable performance.
