Abstract
The problem of the arch loading case is studied by the combination of finite element analysis (FEA) and B-Splines, which provides a highly accurate solution to the calibration problem of the FEA model. Attention is paid to the assessment of FEA by a high-accuracy two-dimensional B-Spline model using point clouds from terrestrial laser scanning (TLS) which is one of the most accurate measurement tools. In the current paper, a B-Spline-based optimized model, comparing to an idealized model, is applied in the FEA. Meanwhile, characteristics of arched nodal displacement and stress are discussed. The target function of the optimization is to reduce the displacement error. It is revealed that the B-Spline optimized model based on TLS data with high-accuracy could carry out FEA efficiently with fewer displacement errors, which is an important part of the automatic calibration of FEA. Finally, the equivalent stress in the post-computation is applied to predict the possible crack regions and carry out the damage monitoring.
