Light weight Prefabricated Roof Element for Long Spans
The goal of this thesis was to study the properties of a new type of roof element for long span building such as a factory and warehouse. Longer beams provide a larger space for the building. The main objective was to study the feasibility of a new type of load-bearing element. Main issues were to design a beam that is strong enough to carry the load over such long span and to resist the bending moment due to the length of the span. Furthermore, the structure had to be strong enough to resist failure at support and deflections. In addition, the whole structure has to be economical, light and able to be made with the existing work process. The thesis consists of the theoretical part and practical part. The practical activities took place in the Sheet Metal Centre(SMC), and all material and equipment for the manufacture and test were provided by SMC. Firstly, surveying and studying of existing roof elements was done. Then, several possible solutions were designed according to the surveying. The loading bearing capacity of the specimens was calculated by checking its deflection, shear resistance and bending resistance. Then, small-scaled specimens had to be made to demonstrate the behavior of the beams. Specimens were completed by using a combination of various of equipment. The whole manufacturing process contains cutting, bending and fixing. Great attention was paid during the process preventing a negative effect on the final result as much as possible. Then the specimens were taken to the test. Many trials were done before the final goal was reached. Test whole test results clearly indicate the behavior of beams under the load and the effect of beams and insulations.
