Structural Existing Conditions Report
The purpose of this report is to provide a comprehensive description of the existing physical conditions and design considerations of the Tree House Residence Hall with an emphasis on the structure. The information contained in this report is meant to serve as a narrative introduction to the building. Further investigation and analysis of the building will be dependent on the contents of this report.
The purpose of this report is to identify and quantify the structural design loads used in the design of the Tree House Residence Hall. Calculations are organized and compared to known design loads in order to further examine the existing design. Computer models and other more sophisticated methods of analysis in future reports will be verified through comparison with these calculations.
Notebook Submission A - Building Codes, Specifications, & Loads
This report covers typical member spot checks for an interior bay and three investigative analyses of alternative framing systems. Typical members include the composite decking, steel girders, an interior steel column and an exterior steel column. The three alternative systems are two-way flat-plate concrete slab, cross laminated timber (CLT) on glued laminated (Glulam) beams, and hollow core concrete plank on steel girders. A comparison of these systems shows which system merits further investigation.
Notebook Submission B - Typical Member Spot Checks & Alternative Systems Design Study
Notebook Submission C - Lateral System Analysis Study
This report includes analysis of lateral force resisting systems and their associated elements. These elements include: moment frames, lateral braces, floor diaphragms, and drag struts. A structural model in ETABS is used for accurate distribution of loads. However, member checks are performed by hand. This report also discusses the impact of lateral forces on the foundation.
