Structural Depth

The current structural design of Jackson Crossing uses a concrete base supporting a wood truss and bearing wall system. This system was found to be more than sufficient for the design loads determined through Submission A to Submission C.

For a design alternative, a complete concrete system will be investigated for both the gravity and lateral system. The gravity system will be two-way reinforced flat plates suppoted by columns. The lateral system will be intermediate concrete moment frames. While the existing structural system of Jackson Crossing is a light and low cost solution, a concrete structure is worth considering as it is durable and provides a thin floor system. The design alternative will not increase the overall height of the building and will keep the same typical floor to floor height unless the alternative floor system decreases the floor to ceiling height.

One problem with the design alternative is how the added weight of a complete concrete system compared to the existing wood frame system will impact the transfer beams at the ground floor level. One of these critical beams is highlighted in red in Figure 1. In this figure the column transferring loads from the five floors above it is marked with a green circle and an arrow pointing to its location. The existing specifications of the highlighted transfer beam are 48” by 36” with 14 #10 bottom bars and 8 #9 top bars. The loads on this transfer beam from the alternative design will be analyzed to determine the impact of the revised dimensions on the garage level clearance below the beam.

Breadth Topics
Construction Management

The focus of the construction breadth will be the difference in cost associated with a concrete system compared to the existing structural system that contributed to an overall project cost of $16 million dollars. The analysis will consider the cost required for the formwork and material to pour the two-way reinforced flat plats and columns. In addition the cost of labor associated with the alternative design system will be studied. Also, the critical path will be investigated to determine if a concrete alternative requires a longer time period along the critical path compared to the existing system.

Mechanical Breadth
The existing mechanical system in Jackson Crossing is hidden in a floor system supported by 18 inch wood trusses. In areas where the mechanical ducts run parallel to the floor trusses, these ducts are allowed around 18 inches of space minus the thickness of the insulation. The mechanical breadth will explore how the mechanical ducts can resized to maintain both the current floor to ceiling height and the air flow capacity. These conditions are important to provide comfort for the occupants.
M.A.E. Coursework Requirement
To incorporate graduate level coursework, the alternative design will include skills and concepts learned from classes in the Integrated B.A.E./M.A.E. program. The modeling of the lateral system will require knowledge in lateral frame design acquired from AE 530, Computer Modeling of Building Structures. The design of intermediate reinforced concrete moment frames will use lessons learned in AE 538, Earthquake Resistant Design of Buildings.
  Note: While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work in progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Michael Bologna. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.
