Design Study of Prestressed Uplift Cast-in-Place Pile

Abstract:

In foundation, crack width of uplift cast-in-place pile will exceed the limit of code. Reinforcement of piles has to be increased and sometimes the diameter of piles also needs to increase. Thus, reinforcement and crack control of uplift cast-in-place pile and prestressed uplift cast-in-place pile are analyzed by simulation design for the actual working condition. The calculation results show that prestressed uplift cast-in-place pile can not only decrease reinforcing area, but also control effectively the crack width of concrete in pile.
