Reliability assessment of flexible dolphins: Reducing uncertainty in the design approach of flexible dolphins

The abstract outlines a study focusing on improving the design approach for flexible dolphins, vital marine structures used for vessel berthing and mooring. Current design methodologies, particularly those outlined in the CROW C1005 handbook (2018), are questioned due to potential conservatism stemming from insufficiently calibrated partial...

Reliability-Based Partial Factors Considering Spatial Variability of Strength Parameters

The stability of six regional dyke cross-sections in the Netherlands was re-assessed using the random finite element method (RFEM), which explicitly accounts for the spatial variability of strength parameters. The RFEM assessments of the cross-sections were shown to result in significantly narrower response distributions than those obtained...

Reliability analysis of Submerged Floating Tunnels

A submerged floating tunnel (SFT) can be a promising solution for crossing a deep or wide waterway. This tunnel concept will consist of an immersed tube, either attached with anchor cables to the seabed or attached to pontoons floating on the water surface. The reliability of the tether-stabilized SFT is assessed in this research. A suitable...

Assessment of design mechanical parameters and partial safety factors for Wire-and-Arc Additive Manufactured stainless steel

Early investigations suggest that the use of Additive Manufacturing (AM) technologies for construction has the potential to decrease labor costs, reduce material waste, and create customized complex geometries that are difficult to be manufactured using conventional construction techniques. Nevertheless, the full exploitation of AM...

Relationship Between Construction Costs and Reliability of Quay Walls

Structures have to meet a particular level of safety. Therefore, in the European design codes (Eurocodes), three reliability classes (RC) are introduced based on the potential consequence of failure of the structure. For each of the RC a maximum allowable probability of failure is introduced, corresponding to a reliability index. In recent...

Reliability based Assessment of Quay Walls

Uncertainties in the soil parameters play a major role in the design of quay walls. In the current design approach, partial factors are prescribed to account for uncertainties in the soil, as well as for other types of uncertainties. This semi-probabilistic (level I) design approach needs to result in a reliable design for a range of quay...
