Not many glass columns exists in the world, and especially used for buildings. Safety and mass manufacturing is a problem. How can you make sure that a glass column is safe even enough for the public and in what way can it been manufactured? These are two of the seven problems I am faced with during my research. The purpose of this thesis is to look the possibilities of using glass columns to replace the existing concrete columns of the 1st floor of the Civil Engineering faculty at the University of Technology in Delft. First, a study about the different properties of glass will be conducted to gain enough knowledge for designing a glass column. In a detailed central section the research presents methods on how to build a column made of modified Tetris shapes. In conclusion, the results suggests that it depends on the design as some methods are more efficient than the other. Casted glass is often for unusual and irregular shapes. However, it takes a long time for glass to cool down after manufacturing and therefor often expensive in comparison with laminated glass. The latter method is used for the Tetris design.
