7. CONCLUSION
Comparing Eq. 4 to Eq. 7, the design is governed by the earthquake generated base
shear and it can safely sustain a horizontal ground acceleration of 1.68 times the
gravitational acceleration (i.e. 54.1 ft/sec2 ) with a safety factor of 3.0.
This means that the base connection of the shear wall diaphragm will reach the yielding condition at a horizontal ground acceleration of 162.3 ft/sec2 . However, this shear yielding condition will only cause a sliding displacement of the shear wall without endangering the collapse of the building.
This means that in case of extraordinary earthquake beyond the design limit, it is still safe to stay inside the housing unit. This unusual safety feature is mainly due to the very high strength/weight ratio of the composite foam panel system.
