Abstrait: Discrepancies exist between UK design codes for the prediction of pile cap shear strength. A series of reduced scale pile cap experiments to investigate shear strength have been performed. Results from seven samples are presented. Details of test methodology and procedure are shown. Final crack distributions show that pile caps under wall load behave close to simply supported two-dimensional deep beams, except for hogging cracks over the pile head indicating the existence of moment restraint at the piles. Results for failure load indicate that pile cap shear strength is at least two to three times higher than current code predictions from semi-empirical formulae. The truss method is shown to be more reliable to predict pile cap shear strength than bending theory.
