SOLID GEOMETRICAL CHOICES FOR STRENGTH

This acrylic scale model built in 1979 was the inspiration for a 30 year effort in building stronger better prefabricated homes. The configuration variety provided by these identical panels, their angles of intersection providing 3 axis of resistance to lateral forces instead of 2, the multiple orientations of the views provided gave Poirier a rush he could not resist to build them for all these years. Since 1979, a few changes were brought about, the actual rhombic dodecahedron was actually squashed vertically, then some roofs were transformed into 6-side pyramids, but the essential merit of the shape remained intact as the panels and the shells were proven to be equal or more resistive than planned.
This merit is firstly the unusually high resistance to side loads. This diagram makes it easy to understand what makes this possible. Whatever the direction

PERU - Earthquakes don't have to Be Like this - They are non-lethal for those residing in Archimede Houses

The immense tragedy like the one shown above have no reasons to be. These houses are actually slow and expensive to build as compared to Archimede, the latter having an incredible earthquake resistance for the following reasons:

• 30% to 50% less unsprung weight
• All concrete surfaces reinforced with a gauge12 mesh
• All panels joined with similar mesh and armatures
• Connection to floor with shear resistant steel @ 1m O/C
• All openings reinforced with #4 rebars, protecting doors and openings
• All wall are shear walls, yet weigh sometimes less than half of that of regular construction. The axial and perpendicular stress resistance on walls and roof is astounding.
• All roof/ceiling panels weigh sometimes 4 times less than regular roofs, yet are fully reinforced with concrete mesh on both sides.
• Connections between roof and walls has a factor of safety of up to 3.
