RISA-3D was used to quickly evaluate the deflection and free vibration of the bridge in order to determine how the structure would react under various pattern loading conditions as well as failure scenarios of the individual stringers or supporting column. This resulted in various patterned loading conditions that all needed to be evaluated for vibration concerns. Additionally, the 14ft wide stair was divided into two parts: with space for walking and space for seating. However, during the numerous design iterations the decision was made to add one central column to support the structure. Originally, the design called for the bridge to be completely hung from the roof. One of the most challenging aspects of the design was the central atrium bridge.
