Damage Identification of T-Beam Bridge Based on Distributed Long-Gauge Strain Mode Theory
Damage identification of a T-beam bridge which contains five T-beams is conducted based on distributed long - gauge strain mode theory, considering the damage and aging problems of widely used simple-supported reinforced concrete T-beam bridges. Assuming that the damage occurs in the different T-beams, the normalized strain mode is used to identify the damage. The sensitivity of the normalized strain mode of each T-beam and change rule of strain mode curve is studied at the same time. It is effective to apply modal strain amplitude variation degree to detect damages. If sensors are arranged reasonablely, a good damage identification can be obtained by utilizing distributed long-gauge strain mode theory even if the damage is slight.Some suggestions are given for the sensor arrangement and health monitoring of this kind of bridge when using the distributed long-gauge strain mode theory at last.
