Example 11: Deep Pile Cap with Tension Piles

摘要

In industrial structures, deep pile-caps are commonly used. Two approaches (sectional design and strut-and-tie model [STM] design) are presented for designing deep pile-caps under a combination of axial load, shear, and moment that produces tension in some piles. The sectional design method is similar to that used for traditional design of thin slabs or slender footings using the ACI318 Building Code. Several potential problems with the sectional design approach based on ACI 318 Code for deep pile-caps are discussed. The differences in designing and detailing of final reinforcement based on the sectional design and the STM design are discussed.
