| Summary: | Bridge is an infrastructure that withstands dynamic and repetitive loading. The effect
of this loading on the bridge element, especially on Steel Bridge type, there is
repetitive occurrence of stress and relaxation due to vehicle loading in service life
that can make the bridge failed due to fatigue. This fatigue condition can be
evaluated to nominal fatigue resistance in service life, based on AASHTO LRFD
Bridge Design Spesification 2012. The purpose of this research is to evaluate the
fatigue lifetime of steel truss bridge structure due to projection of accumulated
vehicle load from WIM vehicular loads measurement in 2 locations, Pawiro Baru B
Bridge and Pawiro Baru A Bridge, at Batang-Kendal National Highway (2017) and
at Jakarta – Tangerang Toll Road (2016). This evaluation was conducted by using
stress range-number of cycles from structural analysis of accumulated WIM
vehicular load, and compared to nominal fatigue resistances using stress range
cycles-number curve (S-N curve). Evaluation method of fatigue with S-N curve
method are specified in SNI and AASHTO.
The results of the fatigue limit evaluation using WIM data on two locations show that
in a 75-year service period, this Bina Marga standard steel frame bridge class A and
B still has a nominal fatigue load on the S-N curve which has not exceeded nominal
fatigue resistance, so that fatigue damage does not occur during lifetime.
