Conclusion With this optimization a less conservative but fully fulfilling safety approach can be reached. . For the load limit taking account for creep rupture the two reluctant approaches one neglecting live load and the other dead load plus 100% live load could be joined on a scientific probabilistic base depending on the load category.

Fig 4: design according advanced approach shows higher allowable loads (blue against red) For applications with lower probability and duration of variable actions

Fig5: design according advanced approach shows higher allowable loads (blue against red) For applications with higher probability and duration of variable actions This approach can optimize the use of FRP material appropriate on a safe scientifically based probabilistic way. If the design with the EC2 method including all loads is to uneconomical, this method as a future extension of the
