Fiber-reinforced polymer composites have
been used in civil engineering for years, as
replacement material for traditional materials
and are becoming more used in structures.
This raises the need for a design standard for
fiber reinforced polymer composites. However
no Eurocode is available for fiber reinforced
polymer composites.
In this report, fatigue of fiber-reinforced polymer
is investigated in order to calibrate partial
safety factors using probabilistic methods
for a traffic bridge system. The traffic
bridge system is mainly composed of
composites. Characterization of strengths is
achieved through static and fatigue tests using
statistical analysis. Traffic loads are applied
according to DS/EN 1991-2 and uncertainties
regarding the traffic load is modeled
as stochastic variables. The fatigue limit state
is investigated along with a sensitivity analysis.
Based on the fatigue limit state and corresponding
design equation, the partial safety
factors are calibrated to the target reliability
levels for bridges according DK NA.
