Damage Detection on Stay Cables using an Open Source-based Framework for Finite Element Model Updating

An open source software-based solution for Finite Element Model Updating is presented. The calculation technique has been carried out by developing VCUPDATE, a Scilab (MATLAB-like software) code performing the iterative updating algorithm interfaced with OpenSees executing the Finite Element analysis. The code has been verified by many different applications on stay cables. The dynamic test results from real structures are applied if available. Otherwise, the investigated structures are numerically generated by OpenSees.
