Abstract
A structure comprising a vertical load and supporting structure therefor, characterized in that the vertical load supporting structure comprises concrete slab cladding of a reinforced earth structure, said cladding comprising at least two tiers of concrete slabs, and method of construction thereof.
Claims18
A structure comprising spaced support means defining an interior area, an external vertical load laterally spanning the defined area freely supported by said spaced support means, at least one of said spaced support means comprising a first wall substantially supporting the weight of said vertical load and including at least two tiers of vertically stacked concrete slabs, a reinforced earth fill structure generally coextensive with said wall exterior of said defined area and in bearing engagement with said wall, a plurality of flexible reinforcing strap means fixed to each of said slabs and extending laterally into frictional engagement within said earth fill structure said slabs having edge portions abutting corresponding edge portions of adjacent slabs so as to accommodate limited relative lateral displacement of at least some of said concrete slabs of said wall upon subjection of the said structure to lateral blast loading while substantially maintaining the integrity of said structure and supporting said vertical load.
The structure of clam 8 wherein said vertical load comprises a concrete roof.
A structure comprising a laterally and inwardly extending external vertical load, a wall receiving and substantially supporting said vertical load, said wall comprising at least two tiers of concrete slabs placed vertically on top of one another, a reinforced earth fill structure lateral outwardly of said wall, a plurality of flexible reinforcing strap means fixed to each of said slabs laterally engaging said reinforced earth fill structure, said slags having edges formed to cooperate with adjacent slabs for relative displacement between adjacent slabs, said wall supporting the external load even after displacement in response to lateral blast loading.
A method of constructing a freely supported vertical load bearing structure capable of accommodating a lateral explosive blast loading, said method comprising casting concrete slabs to define opposed major faces and a plurality of interconnectable edges, forming a wall by stacking said concrete slabs on their edges in at least two tiers, positioning the edges of adjacent slabs to allow for relative displacement between adjacent slabs upon said lateral explosive blast loading, forming a reinforced earth fill structure to one of said major faces of said wall, anchoring each of said slabs laterally to said reinforced earth fill structure with a plurality of flexible reinforcing strap means, and positioning a vertical load on and extending laterally away from the other said major face of said wall so that said wall receives a substantial portion of the weight of said vertical load.
A method of constructing a sub-surface load bearing structure surrounded by earth fill, including load bearing walls and a freely supported horizontal load, said structure capable of resisting forces resulting from an explosion comprising the steps of:
- casting concrete slabs to define opposed major faces and a plurality of interconnectable edge portions,
- securing a plurality of flexible elongated reinforcing strap means into one major face of each of said slabs,
- extending said flexible reinforcing strap means away from said structure and into the surrounding earth fill,
- stacking said concrete slabs on complementary edge portions to form a flexible wall of at least one lower and one upper tier,
- backfilling earth against said one major face of said slabs for completely burying said flexible straps therein for frictional engagement,
- positioning a vertical load freely supported on and substantially said walls and extending laterally away from the opposite side of said one major face and achieving cooperation between the earth fill and the flexible reinforcing straps to resist collapse of said structure from said explosion whereby the integrity of said load bearing structure is maintained.
