Type of structure

This skycraper is a Frame structure because is constituted by elongate members (beams, columns, bars, crossbars, cables...) forming a frame.

Based initially had the form of a octonary or what is the same: a eight-pointed star.

What specific features have been taken into account and resolved?

To meet local safety construction codes, the towers had to be able to withstand 65 miles for hour (105 km/h) winds. To assure this requirement would be fulfilled, the engineers tested the towers twice within a wind tunnel, first by computer simulation and second by building an actual model of the towers.

STRESSES IN THE STRUCTURE:
Tension, compression and bending


Tension:

•In the beams there are tension because it hold the bridge.






Comprenssion:

• In the towers and in the beams there are compression because the beams hold the bridge and the towers on them.




Bending:

• At the top of the buildings there are bending because the air apply forces on the towers.









STABILITY, RIGIDITY AND RESISTANCE

• This structure is made rigid by : the form of the building and the bridge.
• This structure is made stable by :the bridge, the beams and the foundations.

• This structure is made resistant by : strongs materials (steel and glass).
