| Summary: | Piling is a type of foundation that is used to foundation bridges in weak ground conditions. Manuallydesigning a pile group is often a time-consuming process as the design of pile groups today takes placemainly with simple 2D analyses where limited lateral resistance is used. Pile configuration is selectedbased on experience and some optimization can then be performed manually based on initial results tothen export final pile coordinates for design.Design and control calculation of pile groups takes place mainly by repeated manual calculations, acomplicated and time-consuming process because a pile group must be able to withstand different loadssuch as wind, traffic and dead weight, which means that the calculations are extensive and timeconsuming. Even if this means that reasonable results are obtained, there is still room for better andmore efficient results.The above-mentioned approach has instead taken place through an optimized design by means ofautomation to replace the repetitive sub-steps of the design process. An important part of largeinfrastructure projects is the use of piles and each saved pile results in financial, time and material gains.With the use of an automated design of pile groups, the opportunities for saving money, time andmaterials can be rewarding. In this work, a module has been produced for optimization of dimensioningprocesses for pile groups with the aim of increasing efficiency. The work has shown opportunities tocreate a central script in Grasshopper where parameters for a pile group can be transferred to modelingprograms such as Tekla Structures and Revit and also a connection to FEM-Design for structuralanalyzes. The test results and the comparison with the case study also show that the created module ismature enough to dimension pile groups with regard to lateral resistance.
