A depth study will be performed that focuses on the structural system of 1100 Broadway. The current composite floor system is 30.25” in depth and supporting composite member sizes are controlled by deflections. I propose to study the impact of a one-way mild steel reinforced concrete slab with post-tensioned concrete beams in place of the current composite metal deck and supporting composite steel beam gravity system that is currently in place. Advantages of the proposed system include better economy, reduced floor depth, and reduced deflections. The change of system will in turn require a change of lateral systems. Concrete shear walls will be chosen and designed for the new lateral system.

In addition to an in depth study of 1100 Broadway’s structural system, two additional studies will be conducted in fields of study outside of structures. These include an architectural breadth and a building envelope breadth that focus on the green roof on the historic Key System portion of 1100 Broadway.

RAM modeling programs will be used to design and analyze the proposed concrete sytem. This is an extension of AE 597A (Computer Modeling) and is intended to meet the MAE requirement. Concepts from AE 542 (Building Enclosures) will be integrated into the breadth studies and will also fill the MAE requirement.
