Prestanda hos samverkanspelare : En kvantitativ studie om samverkanspelare är ett bättre val i framtidens byggindustri

Sammanfattning: Background: In a world where awareness in climate change is growing, humans need tofind new more sustainable ways towards prosperity and development. Theconstruction industry today is one of the industries where waste iscreated while pace of innovation is low compared to other industries.Theory: To reduce waste, humans need more technical solutions, for instance whenit comes to durability, materials used and carbon dioxide emissions.These solutions also need to be economically sustainable for companieswanting to implement them.Method: This bachelor thesis investigates how different cross sections ofcomposite columns with steel and concrete behaves compared to moreconventional columns of steel or concrete when it comes to climateimpact, costs, durability, and the total size of the columns in themanufacturing stage. The study focuses on four cross sections ofcomposite columns, two cross sections of steel columns and one crosssection of reinforced concrete. The results are based on strength analyses made in MathCADand a life cycle analysis made in OneClickLCA. All results have been verified through othersoftware and different calculation examples in study literature.Results: The results show that composite beams can reduce costs, climate impactand size compared to the conventional steel columns. Although theconcrete column performs better in cost and climate impact, the composite beam is generallyslimmer and has a higher crack load.
