Abstract

The invention belongs to the technical field of civil engineering, and discloses a CFRP(BFRP) longitudinal bar-GFRP composite stirrup square pipe pile and a design method. Transverse stirrups and spiral bars of a cross section of the square pipe pile adopt GFRP bars; vertical longitudinal bars and pre-stressed bars of the square pipe pile adopt CFRP (BFRP) longitudinal bars; the square pipe pile is provided with two layers of FRP bar cages; an outer FRP bar cage consists of vertical CFRP(BFRP) longitudinal bars and GFRP stirrups arranged on along the outer edge of the square pipe pile; and aninner circular FRP bar cage consists of pre-stressed CFRP(BFRP) longitudinal bars and GFRP spiral bars arranged on the edge of a circular cavity. The CFRP(BFRP) longitudinal bars on the inner side aremainly used for bearing pulling force when the square pipe pile is used as an uplift pile, improves the anti-cracking performance of the square pipe pile by applying pre-stressing force, and improvesthe lateral stiffness and durability of the square pipe pile. Stress bars of the pipe pile of the invention adopt a fiber reinforced composite material rather than steel, so that the corrosion resistance of the pipe pile is strong, and the pipe pile is suitable for the environment, such as deep sea, with strong corrosion.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a CFRP (BFRP) longitudinal bar-GFRP composite stirrup square pipe pile and a design method thereof. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: the traditional reinforced concrete structure is in the harsh service environment typified by the marine environment, and its built-in steel bars will accelerate corrosion due to the continuous intrusion of chloride ions in seawater and sea fog. Make the structure face the problem of insufficient durability prematurely. At present, under the "Maritime Silk Road" strategy, my country has promoted the development and construction of sea islands and artificial islands to a national strategic level, which urgently requires the construction of a large number of ports, terminals, airport runways, towers, lighthouses, ocean platforms and Hospitals, schools, ...
