Abstract EN
This paper investigates field applicability of a new system identification technique of estimating tensile force for a cable of long span bridges.
The newly proposed h-SI method using the combination of the sensitivity updating algorithm and the advanced hybrid microgenetic algorithm can allow not only avoiding the trap of local minimum at initial searching stage but also finding the optimal solution in terms of better numerical efficiency than existing methods.
First, this paper overviews the procedure of tension estimation through a theoretical formulation.
Secondly, the validity of the proposed technique is numerically examined using a set of dynamic data obtained from benchmark numerical samples considering the effect of sag extensibility and bending stiffness of a sag-cable system.
Finally, the feasibility of the proposed method is investigated through actual field data extracted from a cable-stayed Seohae Bridge.
The test results show that the existing methods require precise initial data in advance but the proposed method is not affected by such initial information.
In particular, the proposed method can improve accuracy and convergence rate toward final values.
Consequently, the proposed method can be more effective than existing methods in terms of characterizing the tensile force variation for cable structures.
