CEE434
Students toured the Eisenberg School Addition. This structure has a very
interesting entry that required unusual structural detailing, as well as curved
perimeter walls. The final structure is shown below.
In order to accomplish this, sloped internal steel trusses were used. They were exposed during the tour. The photos show some of the detailing of these features.
Some of the metal deck, wire mesh and shear studs were exposed to understand how a composite floor construction is accomplished.
The curved facade was accomplished through the use of straight steel sections, with the facade hung from this. The steel framing is shown at the interior and center of the structure. Note that this simplifies the steel members, but complicates the connections by requiring skewed details. Also visible is the spray on fireproofing that was required in certain spaces, but not in others (white coating on some columns and beams).
Cladding was being hung on the interior of the structure using a crane that was inside the perimeter. Scheduling the crane to be removed prior to completion of the steel was critical to the project. Cladding connections were slotted to allow for proper fitup tolerances.
Braced frames were included for lateral resistance of the structure. Details are shown, with intumescent paint required for fireproofing at some locations. The bottom photo is looking up at the roofing, showing the horizontal framing required to transfer load along the roof plane (this is looking upward, with the entry way trusses at the right of the photo).
mThe structure was required to be physically isolated from the existing Eisenberg Building (see much earlier tour for the first addition to the south of the structure). The connecting walkways are shown, along with the demolition of hte roof to accommodate the flexible connections and framing for the mid-level door and expansion joint.
Roofing was also being completed, with discussion of the insulation and waterproofing layers, as well as the roof drainage.
