ELEVATED VACATION HOME PRESENTATION

2. Purpose and Background
● Luxurious Vacation Home
● Withstand lateral & dead load
● Location
○ Borrego Springs, California
● Model Substructure & House
Site Layout

3. Conceptual Design
● Substructure
○ Achieve lowest lateral deflection
○ Lightweight and Low cost
○ Satisfy constraints and accommodate
testing rig
○ Chevron braced
● Superstructure
○ Unique
○ Fitting in and standing out
○ Functionality

4. Engineering Concepts
● Braced frame
○ Chevron bracing
○ Materials
● Modeled and analyzed in SAP for deflection
and axial forces
○ Assumptions made
○ Obtained bucking case with hand calculations
○ Both results indicate that it will not buckle
■ Verified with SAP analysis
