The purpose of this study is to establish a digital twin multidimensional model of prestressed steel structures. Whilst current methods can automatically detect bridge objects in points clouds in the form of labelled point clusters, the fitting of accurate 3d shapes to detected point clusters remains human dependent to a great extent. Publisher site| google scholar see in references ], material corrosion, complex loads, and prestress loss, the overall structure or local components show different degrees of damage, resulting in the shortening of its l.

95% of the total manual modelling time is spent on customizing shapes and fitting them to right locations.

Therefore, the mechanical performance and reliability of prestressed structures are very important. However, the longer a structure is in service, the more it is affected by various uncertain factors, such as component failure, temperature effects, loss of prestress, and bar construction error; The research object is the prestressed steel structure during the service period only and the study omitted to consider the safety risk in the construction process.

Experiments on ten bridge point cloud datasets indicate that the method 24 achieves an average modelling distance of 7.05 cm (while the manual method achieves 7.69 cm), and an 25 average modelling time of 37.8 seconds.

However, traditional safety assessment methods for prestressed steel structures involve few sample points, do not provide accurate predictions, and consume substantial human and material resources.

In general, the safety assessment process of prestressed steel structures in service is to determine the change rule of the structure under various damage conditions according to the actual principle of the structure, provide the degree of influence of each damage condition on each member of the prestressed steel stru.
