Engineering structure numerical model calibration method and device, electronic equipment and medium

Abstract

The invention relates to an engineering structure numerical model calibration method and device, electronic equipment and a medium. The method comprises the steps of obtaining an engineering structurenumerical model library of a target project; constructing a plurality of response function mathematical models based on the engineering structure numerical model library and the plurality of positions, the plurality of external effect quantities and the plurality of variables of the target engineering; acquiring multi-source monitoring information of the target project; generating a plurality ofstructure parameter combination sets meeting a preset error based on the plurality of response function mathematical models and the multi-source monitoring information; and calculating a confirmationindex and a singularity confirmation index of the plurality of structure parameter combination sets, and evaluating the engineering structure numerical model calibration credibility based on the confirmation index and the singularity confirmation index of the plurality of structure parameter combination sets. According to the invention, the numerical simulation model reflecting the completeness ofthe multi-source monitoring information of the actual engineering structure can be obtained, and then accurate and effective prediction, evaluation and diagnosis of the actual engineering are achieved.

Description

technical field [0001] The invention relates to the field of engineering structure simulation analysis, in particular to a calibration method, device, electronic equipment and computer-readable medium for a numerical model of an engineering structure. Background technique [0002] Engineering structures involved in aerospace, ships, bridges, automobiles, machinery, water conservancy, construction and other engineering fields have played a vital role in the development of human society. Major engineering structures, such as super-long-span bridges, super-long-span space structures, super-high-rise buildings, large-scale water conservancy projects, large-scale offshore platform structures, and nuclear power plant buildings, etc., have a service life of decades or even hundreds of years. Environmental erosion, material aging, etc. The coupling of disaster factors such as long-term effects of load, fatigue effects and mutation effects will inevitably lead to damage accumulation ...

Problems solved by technology

Since only a unique parameter combination result is obtained each time, the results obtained based on different monitoring information are often different, which will lead to: the evolution process of parameter calibration of different monitoring information cannot be reflected, and the value and role of new monitoring information cannot be reflected , the influence of the accuracy of the monitoring equipment cannot be reflected, the effectiveness of the monitoring system design cannot be reflected, and the dynamic evolution process of the structural system cannot be reflected
