| Zusammenfassung |
| The aim of this paper is to compare the near-fault and far-fault ground
motion effects on the probabilistic sensitivity dynamic responses of two
suspension bridges in Istanbul. Two different types of suspension bridges
are selected to investigate the near-fault (NF) and far-fault (FF) ground
motion effects on the bridge sensitivity responses. NF and FF strong ground
motion records, which have approximately identical peak ground
accelerations, of the Kocaeli (1999) earthquake are selected for the analyses.
Displacements and internal forces are determined using the probabilistic
sensitivity method (PSM), which is one type of stochastic finite element method.
The efficiency and accuracy of the proposed algorithm are validated by
comparison with results of the Monte Carlo Simulation (MCS) method. The
displacements and internal forces obtained from the analyses of suspension
bridges subjected to each fault effect are compared with each other. It is
clearly seen that there is more seismic demand on displacements and internal
forces when suspension bridges are subjected to NF and FF ground motion. |
