Summary: | The invention is applicable to the field of highway bridge detection. If a bearing or telescopic device disease causes a joint concave and convex dislocation, under the coupling excitation of concave and convex steps and a driving dynamic load, the torsion vibration response of the telescopic device or a beam body is caused. The invention discloses a highway bridge expansion device torsion resistance service performance evaluating method. According to the method, a torsion vibration data acquisition module is used for collecting the torsion dislocation of the telescopic device or beam body and a torsion vibration response signal, a torsion resistance performance evaluation model which defines torsion resistance performance and the calculation method of a torsion resistance performance degradation rate, a torsion resistance performance degradation performance process database which stores the torsion resistance performance of each detection period evaluated object and a torsion resistance performance degradati |
