03. STRUCTURE 3.4 Improved structure Afterwards the presentation, several adjustments had to be made to the structure. There could be chosen for different scenario’s: Scenario 1 - Remove the columns Removing the columns would be a drastic solution, but is a realistic option. By making the truss system more rigid, the cable-stayed structure becomes superfluous. The big concession which has to be made is the derogation of the architectural value of the total stadium. Scenario 2 - Relocate the columns By relocating the column, the architectural image will not be affected but the urban plan has to be redefined. The angle of the steel cables have to become more steep, so the columns will have to be relocated, become higher, and less steep. Besides this, an ideal location for the base structure has to be found, based on the structural function. This will affect the urban plan, but this has to be accepted to keep the architectonic value. As can be seen on figure 29 there has been chosen for scenario 2. The image which was created proved to be a good one, and removing the columns would affect the stadium too much. Based on GSA values, the columns were relocated until the following values were provided: - The cable-stayed structure has to be in tension before it will fully function. - The location of the columns has been changed compared to the first version. The columns are placed closer to the stadium to shorten the cables. - The columns made more steeper. - The base structure was relocated to their optimal location, based on tension.
