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 Christopher Ankeny. 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 Assigment 1:

Technical Assignment 1 examines the designed structural systems for the Howard County Hospital Addition. It includes detailed descriptions of the floor, roof, lateral, and foundation systems. Also, the codes and material properties utilized for design are listed and referenced.

Calculations were performed to determine the building's gravity and lateral loads, then spot checks of typical elements were done to check the adequacy of various member. Appendices are included at the end that include calculations and spreadsheets for the report.

Technical Assigment 2:

Technical Assignment 2 investigates the existing composite framing and four alternate floor systems. The systems explored were:

1. Existing Composite System

2. Two Way Concrete Flat Plate

3. Two Way Concrete Flat Slab

4. Open Web Steel Joists

5. Hollow Core Precast Planks

Calculations were performed and design aides were used where applicable to design a typical bay. A spreadsheet summary compares and contrasts the five different floor systems.

Technical Assignment 3:

Technical Assignment 3 is a lateral analysis of the hospital addition. Seismic and Wind load cases were checked to identify the controlling case. Estimates were made as to how the lateral loads are distributed to each of the 19 moment frames. These values were compared to those obtained through a RAM model. Drift was checked for both load cases. Finally, spot checks of typical lateral members were performed in order to verify the accuracy of the computer model.
