Abstract

Seismic isolators are the common methods to improve the seismic performance of cable-stayed bridges. Roll-N-Cage (RNC) Isolator is one of the modern systems in recent years. In this paper, it is aimed to study the damage probility and reliability of cable-stayed bridges isolated with Roll-N-Cage (RNC) instruments. For this purpose, Bill Emerson Bridge is selected and based on the Monte Carlo method, damage probility assessment is performed under artificial seismic records and initial imperfection as cable loss. Artificial records have been produced with a proper distribution of random data based on the frequency content and duration of the earthquake and also according to the model of the spectral density function of the earthquake with the dominant Kanai-Tajimi frequency. Nonlinear time history dynamic analysis under the mentioned records are performed for 2000 random samples in accordance with the Monte Carlo method in the form of modeling in MATLAB and Opensees software. The results show that without initial imperfection, the bridge has proper vibration and isolator performance. The failure is observed only in the form of minor permanent deformations of the deck at the end of the vibration. The probability of failure of the cable-stayed bridge without initial imperfection is about 1%, which has a reliability index of 2.3263. By applying an initial imperfection in the middle cable of the middle span of the model, under some records, it experiences a complete collapse. In these conditions, the probability of failure is 2.81% and the reliability index of the bridge is 1.911.
