Abstract:
The beam-column moment connection structure provides secure connection between structural beams and columns, such as conventional I-beams. A first bolt is secured to an upper beam flange at a second end of a beam, where the first bolt extends laterally. Similarly, a second bolt is secured to the lower beam flange at the second end of the beam and also extends laterally. A first block is secured to an exterior face of a first column flange of the column and has a first slot formed therein. Similarly, a second block is secured to the exterior face of the first column flange and has a laterally extending second slot formed therein. The first and second blocks are spaced apart and configured such that the first bolt is received in the first slot and the second bolt is received in the second slot to secure the beam to the column.

Various structures having beneficial uses are described, including compressed air storage facilities and a pumped hydroelectric facility, including such a facility adapted for use with a lock system of a waterway.
Abstract:
Protective barriers for protecting assets (e.g., electrical power transformers and other substation components). The protective barrier may include a lower portion and an upper portion. The lower portion may include first and second laterally spaced A-frame structures having a first protective member assembly extending between aligned legs of the respective A-frame structures on one side thereof. The first protective member assembly may include a first plurality of substantially horizontally extending protective members oriented at an angle relative to a horizontal plane. The first and second A-frame structures may have a second protective member assembly extending between aligned legs of the respective A-frame structures on an opposing side thereof. The upper portion may comprise a third protective member assembly. Methods of making a protective barrier are also disclosed.
Abstract:
A containers shelter is formed from a base array of 20 ft containers, having a sheltered inner area therebetween, and, from a second floor of 40 ft containers that are connected to the base array of containers and cover entirely the sheltered inner area. The containers are filled with a filling material. The base array comprises an entrance container having an inner opening that is transversely directed to an outer opening.
Abstract:
The present invention relates to a panel assembly adapted to absorb a blast effect. The panel assembly includes a panel adapted to be displaceably mounted to a frame, an extendable connecting assembly extending from the panel and adapted to be connectable to the frame so as to mount the panel to the frame, the extendable connecting assembly is adapted to extend in a longitudinal direction and in a controlled manner, such that the extendable connecting assembly includes, a controlling portion connected to the panel, and a connecting portion adapted to be connectable to the frame, the connecting portion glidably coupled to the controlling portion, such that the controlling portion is adapted to control the extension of the connecting portion from the controlling portion, such that the extendable connecting assembly is adapted to extend in a controlled manner to control the movement of the panel when receiving the blast effect.
Abstract:
A structural assembly for use in building applications is disclosed. The assembly has spaced inner and outer face sheets, as well as one or more intermediate panels positioned between the inner and outer face sheets. The assembly provides an enhanced ability to dissipate blast or projectile impact forces and to carry the forces throughout the assembly, thus maintaining sufficient structural integrity in the building to enable the occupants to evacuate, to enable contents to be evacuated, and to enable reuse of the building itself.
Abstract:
A personal safety system with a security entrance (4), a holding room (5) connected to security entrance (4), an air curtain device (2) at an entrance door (3) of the security entrance (4), allows a persons to reach the holding room in a short time. To accomplish the object a circulating air system (13, 15, 18, 19, 20, 22, 25, 26) is provided for the interior space enclosed by the security entrance (4) and for the holding room (5). The circulating air system (13, 15, 18, 19, 20, 22, 25, 26) includes at least one air delivery unit (18) and a toxic gas filter (19), an air flushing device (28, 30, 31) with air storage units (29) for the holding room (5) and a gas supply duct (27) in the holding room (5) for respirator products.
Abstract:
A modular building removable coupling device for forming an explosion resistant, forced entry resistant, and/or ballistic resistant facility. The coupling device can include two hollow square or rectangular tubings having hollow top sides, a sealing means disposed between the tubings, a fastener connecting the tubings, a roof plate secured to each tubing, and a roof cap disposed over the roof plates. The coupling device can include sealing tubes secured to inner sides of the roof cap. A plurality of explosion resistant, forced entry resistant, and/or ballistic resistant modules can be connected with a plurality of modular building removable coupling devices to form an explosion resistant, forced entry resistant, and/or ballistic resistant facility.
Abstract:
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.
Abstract:
A confinement structure comprises one or more open cells (70) for confinement, in use, of particulate fill materials such as soil, sand or aggregate. The cells (70) comprise walls (72) formed of a composite material comprising a polymeric grid layer laminated to a fabric layer. The walls (72) may be formed from a strip of the composite material comprising one or more living hinges. The cells (70) may be provided with skirt portions (74) that extend from at least some of the walls (72).
