Evaluasi Integritas Sistem Struktur Jembatan Dr. Ir. Soekarno

Dr. Ir. Soekarno Bridge is the long span bridge which to be the Manado city landmark. To calculate the Dr. Ir. Soekarno Bridge’s feasibility, integrated evaluation need to know the bridge physical condition reliability. The purpose of this analysis is for reviewing and evaluating the entire Dr. Ir. Soekarno Bridge integrity. Every structure has natural frequency characteristic, which describes the structure strength, stiffness and integrity. The vibration record data sources are dynamic loading test and accelerometer sensor records. Perception and comfortable level the bridge users evaluated by the vibration record data. Perception and comfortable level the bridge users evaluated by the vibration record data. The accelerometer sensors records on X, Y, and Z directions. The Fast Fourier Transform (FFT) analysis carries out to exchange time domain to frequency domain. The frequency domain graphics filtered by ISO 2631-1 formula. Perception and comfortable level the Dr. Ir. Soekarno Bridge users are still in the comfort condition, so this bridge is proper to pass through the vehicles. Based on the Weibull Distribution, Dr. Ir. Soekarno Bridge has service life until 100 years as long as the plan service life.
