ELEVATED VACATION HOME PRESENTATION

Purpose and Background● Luxurious Vacation Home● Withstand lateral & dead load● Location

○ Borrego Springs, California

● Model Substructure & House

Site Layout

Conceptual Design● Substructure

○ Achieve lowest lateral deflection○ Lightweight and Low cost

○ Satisfy constraints and accommodatetesting rig

○ Chevron braced

● Superstructure○ Unique○ Fitting in and standing out○ Functionality

Engineering Concepts● Braced frame

○ Chevron bracing○ Materials

● Modeled and analyzed in SAP for deflectionand axial forces

○ Assumptions made○ Obtained bucking case with hand calculations○ Both results indicate that it will not buckle

■ Verified with SAP analysis

Aesthetics● Oasis Themed● Balance

○ Symmetrical circular pattern○ Desert color and texture

● Order○ Fits Borrego Desert environment○ Repetition of circular pods

● Integrity○ 360 Rotational House○ Substructure reinforces stability and strength

● Meaning○ Oasis: Calm in midst of chaos○ Embodies an ideal vacation home

Conclusion● Communication and collaboration is vital● Imperfections will happen

○ Minimize and account for imperfections○ SAP Model representation

● Innovative Design○ Desert Oasis○ Maintaining functionality○ Achieves safety standards○ Cost efficiency
