Method for testing and evaluating energy consumption performance of steel-composite material anti-collision facility structure

Abstract

The invention relates to a method for testing and evaluating the energy consumption performance of a steel-composite material anti-collision facility structure. Belongs to the field of road and bridge anti-collision facility testing. According to the step, the steel-composite material anti-collision facility is impacted through the pendulum bob device, and the instantaneous movement speed before the pendulum bob device impacts the steel-composite material anti-collision facility and the instantaneous movement speed after the pendulum bob device impacts the steel-composite material anti-collision facility and is separated are obtained through a speed sensor; the kinetic energy reduction value of the pendulum bob device is obtained through calculation, and the steel-composite material anti-collision facility is evaluated through the kinetic energy reduction value. According to the method, an anti-collision facility energy consumption capacity calculation method based on the instantaneous speed before and after impact and the kinetic energy theorem is provided, and a clear evaluation standard grade is formulated. The evaluation steps are clear and easy to implement, the comparison result is visual, the characteristics of the energy consumption performance of the structure can be fully reflected, the practical requirements of engineering are met, and good guiding significance is achieved for production and development of steel-composite material anti-collision facilities.

Description

technical field [0001] The invention relates to a test and evaluation method for the energy consumption performance of a steel-composite anti-collision facility structure, and belongs to the field of road and bridge anti-collision facility testing. Background technique [0002] With the increasing number of bridges and the increasing demand for shipping, the probability of the piers of channel bridges being hit by ships has greatly increased. Ship collision accident not only threatens the passage safety of ships, but also seriously affects the operation safety of bridges, bringing huge threats to personal safety and property losses, and sometimes even causing ecological disasters. [0003] In order to reduce the economic losses caused by accidents such as ship-bridge collisions and improve the safety of public infrastructure, waterway bridges are currently generally equipped with pier-column anti-collision facilities that combine steel and fiber composite materials (ie steel...

AI Technical Summary

Problems solved by technology

Insufficient energy dissipation capacity of the anti-collision facilities will cause most of the kinetic energy of the ship to be absorbed by the bridge piers, which may cause damage to the piers and even affect the safe operation of the bridge
