The results of the simulations indicate the efficiency and applicability of the presented manual tuning method for updating the finite element model of cable-stayed bridges.

The new aspects regarding effective material and structural parameters and model tuning procedure presented in this paper will be useful for analyzing and model updating of cable-stayed bridges.

Shifting the point of view, the larger structure is called an extension or a superstructure of its substructure.

The finite element method (FEM) (its practical application often known as finite element analysis) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as integral equations.

The updating parameters are selected through the sensitivity analysis which helps to better understand the structural behavior of the bridge.
