AFRY provides engineering, design, digital and advisory services. We are devoted experts in industry, energy and infrastructure sectors, creating impact for generations to come. AFRY has Nordic roots with a global reach. Join us in accelerating the transition towards a sustainable society.   

AFRY with the Buildings business area is, with over 1,200 employees, one of the largest players in Sweden in the real estate sector. Here you get the opportunity to be involved in influencing and creating buildings and accommodation where people can stay and enjoy themselves. For us, safety, sustainability and a prosperous society are important factors where we successfully participate and contribute with creative and innovative solutions - both now and for the future. Making Future, as we say. 

Challenge 

• Wind turbine gravity foundations are a repetitive design which can be automized 
• Cost and carbon emission can be reduced with optimizing the reinforcements using Markov Matrix for fatigue design 

Objectives 

• Create a general calculation program using phyton and jupiter which does the following tasks: 
• Receives the load input, calculation of basic geometry for stability, and finds static and dynamic bedding modulus 
• Use the basic geometry and bedding modulus to create a FE model using API to analyze the foundation and extract internal forces 
• Designing the reinforcements based on extracted internal forces 
• Optimizing the reinforcements using Markov Matrix for fatigue 
• Creates the calculation report  
• (extension of thesis if time permits) inputting the calculation results into Tekla structures/Revit using API to create the geometry and reinforcements and make drawings 

Methods 

• Review requirements regarding concrete wind turbine foundations, and punching and shear design, detailing of reinforcements, local effects and fatigue design (Eurocodes and FIB, wind turbine codes and literature) 
• Making automiation of the process 
• Optimize reinforcements using Markov Matrix 
• Final result (and priorities) 
• A calculation software that automize the design 
• Fully automated calculation report 
• Link to BIM software to automize the modeling process 
• Automizing the drawing creation 

What do you gain 

• Learning a commercial FE software 
• Familiarizing with wind turbine foundations and detailing of reinforced concrete and Eurocode 
• Opportunity for recruitment 
• Estimated time required and number of participants 
• 1 academic semester (about 5 months) 
• Required 2 master students at least 

• Good knowledge about concrete structures and eurocode 2 
• Knowledge about fatigue 
• Experience in programming  
• Experience with FE software (ex SAP2000 or other commercial software)
