Embodiment 1

[0024] A method for analyzing and processing the health of a large-span steel structure in a high-speed railway station. The physical environment of the steel structure in a large-span space is monitored by multiple environmental monitoring devices to obtain environmental parameters; the multiple environmental monitoring devices include at least temperature and humidity , Corrosivity, wind speed, sunshine parameter monitoring. By monitoring the temperature, humidity, corrosion degree, wind speed, and sunshine duration, the service environment of the large-span space steel structure is monitored. Timely determine the impact and risk caused by environmental factors. The long-span steel structure of high-speed railway stations in coastal areas will be affected by high temperature, humidity, and salt corrosion during use, as well as wind speed and sunshine duration.

[0025] The stress-strain performance of the target node is detected by multiple network node detection sensors, a...

Abstract

The invention provides an analysis and treatment method for health monitoring of a long-span space steel structure in a high-speed railway station. The analysis and treatment method for health monitoring of the long-span space steel structure in the high-speed railway station comprises the steps that the physical environment where the long-span space steel structure is located is monitored throughmultiple environmental monitoring devices to obtain environmental parameters; the stress-strain performance of target nodes is detected through multiple network node detection sensors; a three-dimensional model of large-span space steel structure is established through a building information model, and stress-strain information and environmental parameters are identified at the target nodes, thestress-strain amplitude of each target node is calculated, and the health risks of the corresponding nodes are identified and judged in different colors according to the stress-strain amplitude at thetarget nodes. The analysis and treatment method for health monitoring of the long-span space steel structure in the high-speed railway station can monitor the health condition of the large-span spacesteel structure of the high-speed railway station in real time in a simple way and carry out risk monitoring conveniently and visually.

Description

technical field [0001] The invention relates to the technical field of steel structure health monitoring, in particular to a method for analyzing and processing the health of a steel structure in a large-span space in a high-speed railway station. Background technique [0002] At present, high-speed rail passenger station buildings and platform steel structure canopies mostly adopt the form of large-scale, large-span, and complex structural systems such as grids and trusses. For example, Guangzhou Railway Group has Guangzhou South, Shenzhen North, Haikou East, Sanya and other 70 Each station adopts large-span space steel structure. [0003] The steel structure station buildings and platform canopies of high-speed rail passenger stations are different from ordinary civil buildings. Due to the large passenger flow of high-speed rail stations, the main structure and structural components that cannot be replaced during use are designed for durability according to the service lif...
