Title:
BRIDGE INFLUENCE LINE IDENTIFICATION METHOD CAPABLE OF ELIMINATING VEHICLE POWER EFFECT
Document Type and Number:
WIPO Patent Application WO/2020/048090
Kind Code:
A1
Abstract:
A bridge influence line identification method capable of eliminating a vehicle power effect, comprising: (1) preprocessing bridge response data measured by a sensor by using an empirical mode decomposition method; (2) identifying the preprocessed bridge response by using a quasi-static method. By preprocessing the bridge response using the empirical mode decomposition method, a dynamic overlay item of the bridge response can be eliminated to obtain a quasi-static response of a bridge, thereby being used for influence line identification. Moreover, the method can process structural response data measured by the sensor on various bridge types, without knowing any information on bridge structures in advance, and thus has a good engineering application prospect.
