Method for evaluating longitudinal shock resistance of highway bridge support and stretching device
The invention is suitable for the field of highway bridge detection. If a bridge support or a stretching device is damaged, under the excitation action of dynamic loads, the stretching device or a beam body can generate longitudinal shock vibrations. The invention discloses a method for evaluating the longitudinal shock resistance of a highway bridge support and a stretching device quickly. According to the method, a vibration data acquisition module for acquiring a longitudinal acceleration response signal of an object to be evaluated, a longitudinal shock resistance evaluation model which defines calculating and grading methods of the longitudinal shock resistance and the shock resistance deterioration rate, and a deterioration process database for storing the evaluation results of the longitudinal shock resistance and the shock resistance deterioration rate in all detection periods, tracking and monitoring the change of the shock resistance deterioration rate, and diagnosing and identifying the early deterioration and damage of the shock resistance are included. According to the method, the detection efficiency is improved, and the reliability of checking and evaluation is improved.
