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 Daniel Hesington. 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.


Technical Assignment 1

The structural concepts and existing conditions report contains a description of the structural system of the University of North Carolina's Imaging Research Building. The architectural design was discussed to relate the impact on the structure and relate any guidelines or tolerances required to limit compromise of this vision. A full description of the structural system and how the components work together was noted, gravity and lateral loads were determined and hand calculations were done to analyze the design.

Technical Assignment 2
The pro-con structural study of alternate floor systems looks into the existing floor system of the UNC IRB which was designed as a one-way cast-in-place system. The three alternate systems that were analyzed include:

- Non-Composite Steel Framing
- Hollow Core Precast Panels on Steel
- Composite Steel Framing

Technical Assignment 3
The third technical assignment includes an analysis and confirmation of the original lateral system of UNC IRB. The forces were applied to the lateral force resisting system composed of ordinary reinforced concrete shear walls. Torsion, shear, drift, displacement, and overturning were all examined and compared to code and industry limits where applicable.
