Jämförelse av stomsystem för flerbostadshus i förhållande till tid, kostnad och CO2-avtryck

Nord, Thea, Edofsson, Nina January 2024 (has links)
The choice of frame system is one of the first and most important steps in the design process. The decision is based on many key factors, including construction time, cost, and carbon footprint. There are studies that describe the different factors for various structural systems, but none that gather four of the most common systems in the same study. This study, conducted in collaboration with Skanska, analyzes a prefabricated CLT (Cross-Laminated Timber) structure, a prefabricated concrete structure, a hybrid structure combining CLT and concrete, and a combination structure with steel columns and a flat concrete base, in terms of time, cost, and CO2 footprint. Calculations and life cycle analyses have been performed on the four different frame systems, showing that the hybrid CLT and concrete structure performed the best overall in the three categories. The combination structure with steel columns and a flat concrete base followed, then the prefabricated concrete structure, and lastly the prefabricated CLT structure. Interviews with Skanska employees revealed that their knowledge and experience somewhat aligned with the results of the calculations and life cycle analyses, but the attitude towards continuing to work with the relatively new CLT structure was positive. / Valet av stomsystem är ett av de första och viktigaste stegen under projekteringsprocessen. Valet grundar sig på många viktiga faktorer, bland annat hur lång tid de tar att bygga, hur mycket det kostar och hur stort CO2-avtryck det har. Det finns studier som beskriver de olika faktorerna för olika stomsystem, men ingen som samlar fyra av de vanligaste stomsystemen i samma studie. Denna studie, i samarbete med Skanska, analyserar en prefabricerad KL-trästomme, en prefabricerad betongstomme, en hybridstomme i KL-trä och betong samt en kombinationsstomme med stålpelare och plattbärlag med avseende på just tid, kostnad och CO2-avtryck. Kalkyler och livscykelanalyser har gjorts på de fyra olika stomsystemen, vilket visar att hybridstommen i KL-trä och betong var den stomme som i sammantaget presterar bäst i de tre kategorierna. Kombinationsstommen med stålpelare och plattbärlag kom därefter, följ av den prefabricerade betongstommen och sist den prefabricerade KL-trästommen. Intervjuer med medarbetare på Skanska visade att den kunskap och erfarenhet som de besatt i viss mån stämde överens med de resultat som kalkyler och livscykelanalyser visade, men att inställningen till att fortsätta jobba med den relativt nya stommen i KL-trä är god.
