Final Report

The purpose of this thesis was to design a pre-stressed concrete alternative to the existing reinforced concrete two-way flat plate floor slab. Two such systems were investigated. A banded beam system and a two-way post-tensioned flat plate slab were designed. Following that, investigations were made into the possibility of altering the size of the massive 14 x 72 columns from which the cantilever extends, and into the removal of the columns in Row B.

Finally, mechanical and architectural studies were conducted on the enclosure system resulting in a redesign of the system from a brick cavity wall to an EIFS wall system. The goals of the design of the new exterior wall system were to reduce the chance of condensation in the air space (a danger posed by the existing system), reduce the amount of heat loss and gain of the wall, and to create a thinner and lighter system.

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‐inprogress 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 Jonathan Coan. 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.
