Bollhall i Säffle : En jämförelse mellan stål- och trästomme
Sammanfattning: SÄBO AB will construct a sports Centre in Säffle municipality, the sports Centre will be used for football practice and the outer dimension of the sports Centre was determined to be 40x70 m. The purpose was to demonstrate price and carbon dioxide emissions for the production of glulam and steel frames, the cross-laminated timber, CLT, and Paroc curtain wall. This was done by dimensioning the frames according to the Eurocodes and generate producing prices for the materials, also a calculation was made for carbon dioxide emissions for the alternatives in terms of transport and production. To calculate a key figure for earned carbon dioxide per invested capital, the differences could be more clearly demonstrated. Another aim was to produce a design proposal. The glulam frame consists of glulam columns with three-joint truss in glulam, drawstick and windstrut in round steel. The roof trusses have a span of 40 m and the ceiling height indoors is 7.5 m. This frame became the most expensive but more beneficial in terms of carbon dioxide emissions for production. The steel frame consists of HEA columns and saddle framework as roof, the roof trusses have a span of 40 m and the ceiling height indoors is 7.5 m. This frame was the cheapest but has the largest emissions of carbon dioxide from the production. The curtain wall of CLT released the least carbon dioxide but became the most expensive alternative, the curtain wall of Paroc became the cheapest option but released most carbon dioxide from these two alternatives.
