The invention provides a tube-in-tube bridge
tower of a space
hybrid cable net suspension bridge with a parabolic arched
tower cap. The tube-in-tube bridge
tower of the space
hybrid cable net suspension bridge with the parabolic arched tower cap is characterized in that the parabolic arched tower cap with a rigid tie rod is arranged at the top of a tube-in-tube herringbone tower column; one end ofa giant
diagonal bracing is anchored to the
waist of the tube-in-tube herringbone tower column; the giant
diagonal bracing supports the arch foot of the parabolic arched tower cap and forms a racket-like bridge tower structure; a load-bearing steel cable is placed on the tube-in-tube herringbone tower column, and a carbon
fiber space
cable net is anchored on the parabolic arched tower cap to enhance the spatial stiffness of the suspension bridge and realize the cooperation between two groups of cables; a concrete-filled rectangular
steel tube corner column and a grille tubular double-steel concrete composite
shear wall are adopted to form a
tube structure; the tube-in-tube herringbone tower column comprises an outer
tube structure, a core
tube structure and multiple rigid diaphragms. Thetube-in-tube bridge tower of the space
hybrid cable net suspension bridge with the parabolic arched tower cap has various advantages, such as strong
structural rigidity, good wind resistance stability, rich facade modeling, strong
earthquake resistance, and capability of being adopted as a bridge tower structure of a space cable net suspension bridge with a super-
long span of 4000 meters.
