The move required a major tenant improvement to make the building fitting for a well-renowned arts school. Part of the tenant improvement involved the addition of a new cable-supported concrete mezzanine. The architect wanted to invoke the image of a suspension bridge with the mezzanine supports. To stay “true” to the structure the cables could not be solely an architectural element, but needed to support the curved mezzanine edge. Determining the structural loading of the cables and the subsequent optimal cable locations was challenging, as the cables follow a curved form at their top and bottom points and because of the tributary area of loading to each cable varied. To determine the cable locations, the architect first passed a three- dimensional model with their “vision” to the engineer, this was imported into SCIA Engineer and all appropriate loads were applied. The deflected form of the model was determined and nodes were moved to their proper locations based on the loading. This revised model was passed back to the architect. When the final shape was agreed upon, the cables and supporting steel structure above were designed for their final loading.
