PENENTUAN NILAI REGANGAN JEMBATAN SIAK I OLEH KENDARAAN BERMOTOR MENGGUNAKAN FIBER BRAGG GRATING
Abstract: Vibration-induced
strain and natural frequency of Siak I Bridge were investigated in
thisresearch. A Strain was calculated from laser power measured by powermeter.
Natural frequency wascalculated using manual calculation with single-girder
analysis. The research has been done at fivemeasurement points at Siak I
Bridge. The five measurement points were 10 m, 87,5 m, 175 m, 265m, dan 287,5 m
from the one point of the bridge in Senapelan Subdistrict. The car used to
inducevibration was Xenia and the power measurement was conducted in predawn.
The instruments used werelaser diode, Fiber Bragg Grating (λB = 1550 nm), and
powermeter. The results showed that five measuringpoints almost experienced
strain below 20με.
