A shelter system having an erecting frame system and a protective skin system. The erecting frame system has at least two A-frame legs and at least one tensioning element. The A-frame legs each comprise at least one elongated structural member, each of the A-frame legs coalescing with at least one other A-frame leg with at least one connection. The tensioning element is at least temporarily affixed to a free end of each of the at least two A-frame legs, and comprises at least one elongated structural element capable of generating a tension force to draw the free ends of the A-frame legs towards one another, thereby at least temporarily lifting the connection to a predetermined height above the free end of each A-frame leg. A protective skin system is also provided with at least one side plane, one roof plane, and one end plane. The side plane is disposed between two A-frame legs; the roof plane is concordant with the ground surface; and the end plane is disposed between two A-frame legs of a constituent A-frame leg pair and a ground surface. The planar element of the protective skin system provides at least a partial barrier from a ballistic threat to a volume behind the planar element, the loading of the protective skin system being transferred at least in part first to the erecting frame system and ultimately to the ground surface.

A bullet resistant security fence resists impacts from objects, such as vehicles, impacting the fence. A configuration of a bullet resistance security fence can be rapidly assembled and deployed as a riot fence that can be disassembled and subsequently repositioned. The riot fence is stabilized by securement devices that pull adjacent ballistic panels toward intermediate support posts and by adjustably positionable stabilizers that can engage the ground surface in front and in rear of the riot fence, even if mounted on steps. Alternative security fence configurations provide more economical manufacturing and installation by having a ballistic panel between thin front and rear shells. The ballistic panel can be formed of aluminum plate or from multiple layers of ballistic fabric. A ballistic panel can be formed from strips of aluminum plate welded together to form seams that are covered by lathe formed from aluminum plate to maintain ballistic integrity.

Blast resistant shelters and structural designs therefor according to which the structural designs include anchoring systems and manufacturing of the anchoring system. The anchoring systems include at least one bracket with a spiral winding and opposing first and second end portions. The first end portion includes two holes, and the second end portion includes two holes. The spiral winding is disposed between the first end portion and the second end portion.

A glazed façade anchoring system to a building including a box with a connection system to the façade and connection to the building slab. The first and second connections enable relative movement between one another, when the façade moves within the gap between the rear surface of the façade and the building slab edge under the high pressure loads due to exceptional events such as explosions. The device includes one or more solid elements with dissipative components acting in compression in the inward building direction and one or more solid elements with dissipative components acting in compression in the outward building direction.

It is disclosed a densely packable sequential series of external housing units associated with succeeding internal housing units. The external housing units have inside volume and openings for receiving the internal housing unit. Means for facilitating the displacement of an internal unit out of an external unit, like integrated bearings, integrated wheels, integrated retractable wheels, and a low friction coating are installed on an inside shells of the associated external housing unit, on an outside shells of the internal housing unit. The housing units have a uniform cross section along a majority of one of the dimensions of the unit, having outlines like a circle, a triangular frame, a rectangular frame, a circular arc of, a trapezoidal frame, a polygon of five, six or more edges, a hyperbolic arc, and a parabolic arc, or other types of arches. The typical transverse linear size of an internal unit is 80% to 99% of the preceding external unit. The series is transportable as a single cargo item between locations. A shell of an housing unit may include at least one layer like highly insulating layer, anti-ballistic layer, and composite materials such as fiberglass reinforced plastic layer, polymer-metal composite layer, and carbon based composite materials.

A detection apparatus includes: a plurality of accelerometers configured to be installed on respective positions of the architectural structure which are different in height from each other and separately measure an acceleration value generated in the architectural structure; and a computer configured to perform computation by using acceleration values measured by the plurality of accelerometers and detect collision of a flying object (airplane) against the architectural structure when a ratio between the acceleration values measured by the plurality of accelerometers exceeds a first threshold value.
