PROJECT DESCRIPTION
1.1
Elements
The following project uses structural elements as concrete sandwich panels, columns, beams, arch trusses, roof box and metal walls. The building has two meshes: metal sports hall and concrete part, where are situated canteen, shower and toilets, and meeting room. These are connected with corridors. The metal structure has walls and roof made from metal sandwich elements. The roof itself is being supported by glue‐laminated portal frames (For calculations see part 3 – portal frame). In the other mesh, the roof is a box module. The box is made from glue‐laminated rafters and the roof is also a metal profile.
1.2
Loads
The wind from gable ends might be strong for the metal profiles. Therefore, there needs to be wind bracing between the GL framing. The metal wind bracing will be in the edges of the hall on the east and west side (In addition, see truss plan). Also, the loads are taken by the pad foundations according to the calculations given in paragraph 3. As the calculations in chapter 2 will show, the loads can handle a foundation width of 100 mm. Therefore, we are more orientated on the design outcome. The foundations will be 200 mm under concrete exterior panels and 150 under other loadbearing walls. The capacity for soil is 400. The following 3 pages will contain load analysis for the building. These determine point, line and area loads in horizontally and vertically.

PORTAL FRAME ‐ ARCH
3.1 Main data Glue‐laminated trusses are placed in sports hall with the distance of 6 meters apart from each other. Overall span of trusses is required to be 29 m and height of 12 m. The data for loads and dimensions was calculated with a program TOP.
3.2 Data input to program The dimensions were put in program and according to the calculations the portal frame can be 190 x 934 mm in its full length. The following pages will contain information and screenshots on how the results were found. The arch will have a round shape, although it is different in the program. The degree for the arch is 28. The self‐weight of the portal frames is big enough to withstand a pad foundation. Also, the trusses must be reinforced horizontally from the ground – a reinforced bar will be put in the ground supported floor for the trusses to withstand the tension.
3.3
Pad foundations under the frames
In addition, the frame has to transfer horizontal and vertical loads to the pad foundations. The results are following:
We chose the size for the pad foundation before the calculations were made – on foundation plan the size in 900 mm in depth and 1000 x 1000 mm in length and width. The pad foundation is reinforced.
Section through the pad foundation.
Permanent loads acting on the building 87,3 kN/m. Beam suitable for calculating.
Column is 2600 mm in height.
Permanent loads on column 107,6 kN/m. Choice for width and depth.
