Publiceringsdatum2023-11-02Beskrivning av jobbetBackground
• This thesis is the continuation of the previous year's master thesis, to make it more general and cover more details and finalizing the detailed design
• Last year, the python script was created to iterate different alternatives and find optimal spacing of piles due to material cost. The main purpose of this thesis is to make the optimizing based on final costs including execution, etc. and finalize the detail design which was not tackled last year.
Challenge
• Many arrangements of piles/slab thickness and punching solutions can be done
• It is challenging to find optimal solution regarding the final cost and suitability for contractor
Objectives
• Identify different solutions for designing piled slab and enhancing punching capacity
• Develop calculation models for the alternatives
• Optimize the the alternatives with respect to final cost and CO2 emission
• Create smart tables for detailed design of different optimized alternatives
Methods
• Review requirements regarding concrete slab, and punching design, detailing of
reinforcements, local effects, and piles in codes (Eurocodes and FIB, Pålkommisionen, etc.
and literature)
• Summarize examples of piled slabs and their final cost and CO2 emission
• Make FE models of different alternatives
• Optimize regarding the final cost and sustainability
Final result (and priorities)
• A smart chart with load in one axis, and pile depth on the other axis, showing the pile spacing required for optimized design, and containing detailed design
• Multiple charts for different soil type
• Crack calculations (due to imposed loads, and restraint shrinkage).
• Detailing for local effects
What do you gain
• Learning a commercial FE software
• Familiarizing with different punching solution and detailing of reinforced concrete and Eurocode
• Know more about piles and their design
• Opportunity for recruitment
Estimated time required and number of participants
• 1 academic semester (about 5 months)
This thesis can be done with 1 or 2 students.
Kravspecifikation
• Good knowledge about concrete structures
• Some knowledge about piles
• Experience in programming is a good merit
• Experience with FE software (ex FEM-Design or other commercial software)
