Abstract

This study involves analyzing of two piles-caps together with other available tested pile caps in literature. Many expressions are proposed in the current stydy to predict the diagonal cracking and ultimate shear strengths of pile caps using the nonlinear multiple-regression analysis to the available experimental data. The proposed expressions have minimum values of mean absolute error (MAE) and root mean square error (RMSE), while they have maximum values for coefficient of multiple determinations (R2).
For the prediction of diagonal cracking shear strength, two proposed expressions were compared with the available equations. The analysis of pile caps using these equations indicates that the proposed equations results in accurate values closer to experimental results than the available equations. While for the prediction of ultimate shear strength, two proposed expressions were compared with the available equations. The analysis of pile caps using these equations indicate that the proposed equations results in good agreement when compared with the results of the available equations.
