Analys av ett lätt stålbjälklag : svikt, vibrationer och nedböjning.

Abstract
This Masters Thesis’ purpose is to evaluate a number of methods used for dimensioning in order to avoid unwanted sway and vibrations in a light weight steel floor structure. The design methods studied in this report are done by Ohlsson, Hu, Onysko, Talja and ISO (no calculations or measurments are made for ISO). The study shows that there is no big difference in the longest span allowed by the studied methods, with the exception of Ohlsson and Talja. Ohlsson’s Method allows the longest and Talja’s the shortest span. Since there is no big difference between the design methods, dimensioning can be done due to the deflection by a 1 kN point load. The deflection by a point load is hard to estimate and therefore a model is set up to understand... (More)

The deflection by a point load is hard to estimate and therefore a model is set up to understand how the load is spread in the slab. The model seems to have relative good accuracy for longer spans but underestimates the deflection for shorter spans. (Less)
