Design and Analysis of a High-Rise Building.

New York City's various skyscrapers are some of the greatest engineering feats in the world. The design and calculations behind them are the main focus of this project. The building considered for this project is a 567.5 ft-tall mixed-use tower to be located at the corner of West 45th Street and the Hudson River Greenway. The building consists of 15 office floors, a transfer/mechanical level, 30 residential floors, a penthouse, and an elevator machine room. The office floors use a steel-framed system with steel beams supporting concrete on metal decks. Between the steel and concrete elements of the building's structure will lie a mechanical transfer floor that will assist the building's load path, as the steel columns above it aren't aligned with the concrete columns, necessitating the transfer floor. Above the transfer floor, there will be 30 residential floors that utilize a reinforced concrete two-way slab system. A concrete core will also provide stiffness to the building against lateral loads and will vary in size along the building's height. To design a project of this magnitude, we used software tools to facilitate our calculations and modeling. These programs include Excel, ETABS, Bluebeam, and AutoCAD. For the specific design criteria followed, we used the NYC Building Code 2022 in accordance with IBC 2015, ASCE 7 -16, AISC 360-16, and ACI 318-14. From the codes, the building blocks for the project could be formulated, including gravity loads, column analysis, cost estimation, steel framing, deck design, etc. In short, our main objective for this project is to apply the fundamental theories and concepts we learned throughout our time as engineering students to the design of a real-world structural engineering application.
