EXAMPLE 9: PILE CAP. IN: EXAMPLES FOR THE DESIGN OF STRUCTURAL CONCRETE WITH STRUT-AND-TIE MODELS

The example given in this paper illustrates use of strut-and-tie models (STMs) for design of a pile cap. Two load cases are considered: axial load only, and axial load and overturning moment. The design is based on Appendix A of ACI 318-02. Results are compared to section design procedures per ACI 318-99. Compared to section design methods, STM design is more rational and leads to a more reliable structure. Because the reinforcing bars are located above the piles, overall footing depth is increased compared to traditional design in which the bars are placed between piles.
