STRUCTURAL CONTROL OF LALI CABLE-STAYED BRDIGE

With the length of 460 m, Lali Bridge is regarded as the longest cable-stayed bridge in Iran. It is located in Khouzestan Province and crosses the Karoun River. Because of the great importance of this bridge and the earthquake-prone area in which it is located, its seismic behavior is by far an essential issue which should be investigated precisely. Therefore, it is necessary to use a powerful finite element software to achieve a comprehensive model of the Lali Bridge. The model must be capable of simulating the complex nonlinear behavior of different types of elements, especially the reinforced concrete (RC) and pre-stressed cable elements. Vibration control of such important structure is considered as a beneficial and economical method in order to reduce hazard probability.
