This study investigates an adaptive-weighted instanced-based learning, for the prediction of the ultimate punching shear capacity (UPSC) of fiber-reinforced polymer- (FRP-) reinforced slabs. The concept of the new method is to employ the Differential Evolution to construct an adaptive instance-based regression model. The performance of the proposed model is compared to those of Artificial Neural Network (ANN) and traditional formula-based methods. A dataset which contains the testing results of FRP-reinforced concrete slabs has been collected to establish and verify new approach. This study shows that the investigated instance-based regression model is capable of delivering the prediction result which is far more accurate than traditional formulas and very competitive with the black-box approach of ANN. Furthermore, the proposed adaptive-weighted instanced-based learning provides a means for quantifying the relevancy of each factor used for the prediction of UPSC of FRP-reinforced slabs.

In this article, the response of nine plain concrete panels to an impact of hard projectiles was examined in an experimental study. The tests were planned with an aim to observe the influence of compressive strength on the performance of concrete under impact loading. Concrete panels with compressive strengths within the range of 26 to 92 MPa subjected to impact by 23 mm hard projectile at velocities within the range of 270 to 348 m/s were studied. Also, using a glass fiber reinforced polymer sheet, as a liner on the rear face of the plain concrete panel, to strengthen the panel was examined. The experimental results indicate that strengthening concrete panel with a rear glass fiber reinforced polymer sheet showed more satisfactory performance under the impact load than increasing compressive strength of concrete. Also, the use of glass fiber reinforced polymer sheets as rear liners in addition to increasing the concrete strength showed superior performance of concrete panels against impact; it is recommended to be used in protective structures.
