Påbyggnad av våningsplan medlättkonstruktion : En jämförelse av stommaterialen trä ochtunnplåt

Sammanfattning: The purpose of this thesis is to examinethe possibilities for adding a floor to anexisting building using the two materialswood and sheet metal profiles as the loadbearing structure. An apartment buildingfrom the 60s has been used as referencehouse. Two different suggestions for thedesign are presented in the rapport. Oneof them has been analyzed with wood andsheet metal as the load bearing structure.Using the old constructional calculationsand blueprints of the existing buildings,the load bearing capacity has beencalculated. In the calculation programFEM-Design the building has been testedwith the loads that an extra floor wouldgive. From this, a conclusion has beenmade whether the existing building couldmanage an extra floor. Using the 5-Dprogram Vico, a cost calculation has beenmade of the load bearing structure forboth materials. The costs have then beencompared and analyzed.
