Steel structure engineering real-time monitoring and early warning method based on BIM

Abstract

The invention provides a BIM-based steel structure engineering real-time monitoring and early warning method. The system comprises a BIM model processing subsystem, a structure analysis and service center subsystem, a communication network subsystem and a data acquisition equipment terminal. Based on a building structure finite element model based on a BIM data model and real-time sensor data provided by a data network, the structure is accurately simulated and analyzed, any existing or potential structure problems are judged, early warning information is sent out, and problem components are clearly identified in the BIM model through different colors; meanwhile, structural deformation data, external environment data and the like transmitted by the equipment terminal are collected and automatically added to the BIM informatization model, and the model is synchronously adjusted and changed according to structural deformation. According to the invention, high-precision steel structure engineering health monitoring is realized, and the authenticity of structure monitoring and the accuracy of risk analysis are improved through continuous self-adjustment of the BIM model.

Description

technical field [0001] The invention belongs to the application field of building information simulation technology and steel structure engineering quality and safety monitoring, and specifically relates to a BIM-based real-time monitoring and early warning method for steel structure engineering. Background technique [0002] BIM is the abbreviation of Building Information Modeling, that is, building information model, which integrates the geometric information and non-geometric information of the building structure into a three-dimensional visualized digital model for the application of the whole life cycle of the building. [0003] The quality and safety of steel structure engineering during installation and use after installation has always been the focus of the industry, because building structures will be affected by weather (wind, temperature and humidity, solar radiation, precipitation), earthquakes, and the surrounding environment. The finite element model is establi...

Problems solved by technology

[0005] (1) The external environmental conditions of the building structure are constantly changing. The analysis done in the design stage does not truly reflect the external application received in the structure installation and use stage. The real-time monitoring data is not calculated and analyzed in real time, and the early warning is only carried out after a problem occurs. Maintenance, did not achieve real-time risk monitoring and early prediction

[0006] (2) The structure has been deformed, but the theoretical design model is still used for calculation and analysis. The calculation results are distorted and do not truly reflect the current situation of the building
