Problem Statement• Key design consideration: opening the hotel as soon as possible
• Erection of concrete system slow and labor intensive
• Swallower mat foundation will provide cost and schedule savings• Extremely heavy concrete core requires a 9’-0” thick mat foundation
Why was a concrete structure the system of choice?
![Page 11: Trump Taj Mahal Hotel Atlantic City, New Jersey](https://reader035.fdocuments.net/reader035/viewer/2022062722/56813af6550346895da37b23/html5/thumbnails/11.jpg)
Design Goals• Reduce structure dead weight using an all steel
system• Premium 1: 10” floor to floor height increase• Premium 2: Architectural Impacts
• Eliminate costly concrete construction with faster steel erection
• Utilize a “core only” lateral force resisting system
• Determine why a concrete framing system was chosen over a steel framing system?

Structural Redesign
Steel Braced Frame CoreSolution to RMS Acceleration Issue• Already sufficiently large braced frame members require supplemental mass
and damping• Building motion can be alleviated by additional mass and damping
Tuned mass dampers will add approximately $2 to $3 Million to overall project cost

Conclusions• Long lead time for steel and precast planks offers little schedule
advantage (approximately 1 month less than concrete)
• Braced frame core performs adequately against strength and drift
• Lighter steel frame still requires 9’-0” thick mat foundation
• Building accelerations may be perceived by occupants because braced frame core is too flexible
• Steel structure will cost approximately $5.5 million more than concrete structure if mass damper is found to be required
![Page 37: Trump Taj Mahal Hotel Atlantic City, New Jersey](https://reader035.fdocuments.net/reader035/viewer/2022062722/56813af6550346895da37b23/html5/thumbnails/37.jpg)
Recommendation
• Because it is stiffer, the concrete shear wall core limits the dynamic movement of the building better than the steel braced frame core
• Filigree flat plate system erects much faster than a typical concrete floor system, giving the steel little schedule advantage
• With supplemental damping taken into consideration, the concrete system will cost less than steel structure
