Tornado resistant Houses With Insulated Concrete WallsCast in place concrete walls can be formed with steel, wood or insulating foam boardsThe advantage of using insulating forms, called ICFs, is that the finished product accomplishes both a structural and energy conservation function simultaneouslyFor prefabricated walls, purists will
Disaster resistant Shells The wall roof cross section details shown on this website do not necessarily represent the only methods for building a disaster proof houseInstead, they illustrate proven solutions to the problem of building houses that are sustainable, with high resistance to powerful winds, earthquakes, fire, termites and critters.
The previously cited link to the ACI Concrete International magazine ("Disaster Resistant Shell Houses" [PDF], May ) shows different stages of the assembly of an all concrete disaster resistant houseJoint details must positively connect the roofs to the walls and to the foundations.
The evidence clearly demonstrates that buildings constructed with reinforced concrete floors, roof, and walls constitute the only Disaster Resistant Shells that have withstood everything that nature can unleash against man made structures over the past years.
Disaster Resistant Shells In order to assure that the concrete shell structure will develop its full capability to resist imposed destructive forces, it is essential that the roof structure provide a competent structural diaphragm incorporating a cast in place reinforced concrete slab or well connected precast concrete planks in order to
non insulated disaster resistant shell low income house constructed under a California program for housing migrant agricultural workers in Below is a suggested floor plan of the home shown above, developed by the California Department of Housing and Community Development for housing migrant working families.
Design ConsiderationsThere are a number of design restraints that must be observed in order to create a disaster resistant reinforced concrete shellWalls must be engineered as shear walls in their in plane dimensions, and for the out of plane bending moments imposed by wind pressures perpendicular to their plane.
