Themodel tuning through sensitivity analysis is a prominent procedure to assess the structural behavior and dynamic characteristics\r\nof cable-stayed bridges. Most of the previous sensitivity-based model tuning methods are automatic iterative processes; however,\r\nthe results of recent studies show that the most reasonable results are achievable by applying the manual methods to update the\r\nanalytical model of cable-stayed bridges. This paper presents amodel updating algorithm for highly redundant cable-stayed bridges\r\nthat can be used as an iterativemanual procedure.Theupdating parameters are selected through the sensitivity analysis which helps\r\nto better understand the structural behavior of the bridge.Thefinite elementmodel of Tatara Bridge is considered for the numerical\r\nstudies. The results of the simulations indicate the efficiency and applicability of the presented manual tuning method for updating\r\nthe finite elementmodel of cable-stayed bridges. The new aspects regarding effectivematerial and structural parameters andmodel\r\ntuning procedure presented in this paper will be useful for analyzing and model updating of cable-stayed bridges.
