Abstract

A novel buckling energy consumption prevention pipe comprises an outer constraint pipe, an inner core energy consumption pipe and a cover plate; the inner core energy consumption pipe is arranged in the outer constraint pipe in a coaxial clearance manner; at least two rows of energy consumption devices are arranged on the inner core energy consumption pipe in the circular direction, and at least two energy consumption holes are formed in each energy consumption device; longitudinal stiffening ribs are arranged at the positions, between the adjacent rows of energy consumption devices, of the inner core energy consumption pipe, and transverse stiffening devices are arranged between the adjacent longitudinal stiffening ribs; and the two ends of the outer constraint pipe are fixedly connected with the cover plate, and the two ends of the inner core energy consumption pipe stretch out of the cover plate and are in sealed connection. The invention further provides a manufacturing technology of the novel buckling energy consumption prevention pipe. The novel buckling energy consumption prevention pipe and the manufacturing technology of the novel buckling energy consumption prevention pipe have the good ductility, good anti-fatigue performance, good impact resistance performance, good stability, good durability, good bearing force, and good energy consumption performance.

Description

technical field [0001] The invention relates to an energy-dissipating tube and a manufacturing process thereof, which are applied in the fields of bridge engineering, ocean engineering and construction engineering, and are especially suitable for structures in earthquake areas in the above fields. Background technique [0002] In recent years, with the continuous development of the national economy, large-span, super-high, offshore platforms and space structures have sprung up in my country. Among them, many structures are composed of steel pipes as the basic unit components. Steel pipe components are prone to overall instability before the bearing capacity is destroyed, which will lead to structural damage. In order to prevent this damage, the common methods are: 1. Increase the effective section of the steel pipe; 2. Increase the grade of the steel; 3. Fill the steel pipe The concrete forms the CFST member. However, the above two methods have the following defects: 1), th...
