Despite many investigations on the spatial strut-and-tie mechanical mechanism on pile cap punching failure at present, little has been reported on its application. Meanwhile, compared with the steel-reinforced concrete structure extensively existing in the superstructure, that in the foundation structure is yet seldom seen. The real section steel truss of better material properties was used to replace the virtual truss originally regarded as the concrete stress flow for this reason. Aiming at the punching-force bearing behavior of this kind of ...
