Abstract
   Pile caps are crucial element for transmitting superstructure and substructure loads to the piles. The work presented in the thesis is dealing with concentric loaded pile caps,attached to pile groups symmetrically arranged about the column. The applied loads acting on pile cap resulted highly nonlinear strain distribution. The work presented is focused on the analysis of concentrically loaded pile caps using sectional approach, based on empirical formulas for flexural element, and, also, using strut and tie model. The two methods were calibrated with laboratory test results on pile caps published by different authors. Special attentions were given to the justifications of Egyptian code of practice for reinforced concrete provision dealing with the design of pile cap, with the laboratory test results. The same considerations were applied on ACI 318 provisions.
The work was focused also on the design of pile caps using strut and tie model. The thesis presented solved problems for obtaining thickness and reinforcement of pile caps attached to two, three, four, six and nine piles arranged symmetrically about the column.
The problems were solved using ACI code implementing code defined critical section and strut and tie model. The object of the solved problems is to conduct a comparison between the outcome from the two procedures with respect to pile cap depth and reinforcement. Finally, the strut and tie model was presented in three dimensions and the forces in strut and tie model were obtained using commercial software. Comparison between forces in strut and tie using two and three dimensional models was conducted.
