Abstract

The invention relates to a vertical force measurement bridge bearing and a force measuring method thereof. Through measurement and whole demarcation of local stress, the whole stress of the bearing is determined. The bridge bearing is simple in structure, size increase and weight increase are small, force measurement is reliable, the vertical force measurement function of the bridge bearing can be realized, the vertical force measurement difficult problem of the bearing is solved, and technical support is provided for bridge monitoring.

Description

technical field [0001] The invention belongs to the technical field of bridge structures or buildings, and relates to a bridge support with a vertical force measurement function and a force measurement method thereof. Background technique [0002] With the increase of highway and railway bridge construction in our country year by year, the test and monitoring of various loads of bridges, including static, dynamic and impact loads and other vertical loads, are of great practical significance to the operation of bridges. Realizing the monitoring data collection of the bridge support, that is, the vertical reaction force of the bridge, can provide a technical basis for the health monitoring of the bridge. [0003] At present, there are few bridge supports with vertical force measurement function. "A Spherical Multidirectional Force Measurement Support" (Patent No. CN102912772 A) realizes force measurement by setting standard sensors laterally on the pressure-bearing wedge-shape...
