Abstract
The bridge load test analysis system BLT is a special software for the bridge load testing developed by the Highway Research Institute of the Ministry of Transport. It can quickly and easily establish the finite element model of the bridge structure space, and use the solid element and space beam method for static and dynamic test analysis. According to the load test procedure, it can automatically recommend test conditions and layout points, automatically calculate the test load layout, conveniently extract the theoretical calculation values of stress and displacement at the position of the measurement point, and quickly browse the stress and displacement cloud maps. The system is highly intelligent, greatly improving the efficiency of bridge load detection and bringing good news to bridge load test engineering. This paper introduces in detail the characteristics of the intelligent analysis technology, calculation principle and real bridge application examples of the system.
