Abstract

The invention discloses a girder structure deflection calculation method and is applied to theoretical calculation. The girder structure deflection calculation method is characterized by comprising the following steps of classifying load types; inputting or reading a theoretical midspan deflection calculation formula and a theoretical deflection calculation formula for a position apart from midspan by a set distance according to the load types; calculating a difference value of the theoretical midspan deflection calculation formula and the theoretical deflection calculation formula; substituting the difference value into the theoretical midspan deflection calculation formula to obtain a midspan deflection calculation formula containing the difference value; and measuring, inputting or reading the difference value, and substituting the difference value into the midspan deflection calculation formula containing the difference value to solve a theoretical midspan deflection. The inventiondiscloses a device and a system for measuring the girder structure deflection, and is capable of solving the problem that a stable supporting point is inconveniently provided to deflection measurement when a vehicle is driven under a bridge or the bridge encounters a river valley.

Description

technical field [0001] The invention relates to the field of bridge measurement, in particular to a calculation method, device and system for beam structure deflection. Background technique [0002] As we all know, with the rapid development of the economy, the traffic volume borne by bridges increases at an alarming rate, and with it, the fatigue deformation produced by the bridge structure continues to increase and accumulate, which will eventually affect the performance of the structure. Bridge structural deflection detection is an important method to evaluate the degree of bridge deformation and an important link to ensure structural safety. Important indicators and basis for the safety status of bridge structures. [0003] The traditional detection method is mainly based on the deflection detection with supported displacement sensors, including dial indicator, level gauge, total station and displacement gauge. Its advantage is that the measurement method is relatively ...
