Vindstabilisering av SIPS byggnader i Sverige

Sammanfattning: This work is about wind stabilization of a SIPS building in Sweden where the focus is onhow joints take place between the foundation plate and the walls. SIPS (Structural insulatedpanels) is a load-bearing insulation element used to build the entire building envelope. It is anewly arrived building technology in Sweden that is used for passive houses in order toreduce energy use. The elements are prefabricated and bonded together with fiberglassbeams, which are also used to reinforce openings in the building. The method that will beused in this work is the finite element method using a computer program FEM-design by thecompany Strusoft. In the programme the model was rebuilt and calculated according to theEurocode. In collaboration with SIP's company Avis Building technology, the building andthe joint were modeled according to one of their buildings, which was then analyzed. Thisresulted in the joint consisting of screws attached to a profile of aluminum. The result gavethe shear and normal forces that affect the screw and plat. In this way, the question of how anattachment of a SIPs building can take place has been answered. The results in FEM-designshow that a SIPS building can be wind-stabilized in Sweden with the exception of certainparts that can be supplemented with a load-bearing inner wall to achieve full stabilization.But this question cannot be answered with complete certainty without more data and researchon the element being. Too many parameters about the properties of the elements wereunknown, which led to uncertainty. In the program, the building was stabilized but had toolarge deformations in some places. This does not mean that such a building cannot bestabilised, but more research must be carried out before the conclusion can be drawn. In thework, no tests were made of the element, which contributed to this uncertainty. With moremeasurements and trials, a SIPS building can definitely become a future building technologyin Sweden.
