When applied to the steel structures, the prefabricated structural system includes a plurality of steel structure joints and related members. The steel structure joints and related members further comprise: a beam-column connecting sleeve, comprising a first box-shaped steel tube and first C-shaped sleeves extending from and perpendicular to outer surfaces of the first box-shaped steel tube, wherein the first C-shaped sleeve is provided with first wedge shaped recesses at ends of upper and lower flanges thereof; columns, having a column connecting end inserted into the first box-shaped steel tube; main beams, having a main beam connecting end inserted into the first C-shaped sleeve; and main beam fixing steel plates, provided with first wedge shaped protrusions that are tenon-mortise-jointed with first wedge shaped recesses at both sides of the first C-shaped sleeve. In addition to the steel structural construction, the beam-column connecting sleeve of the prefabricated structural system may be further extended to reinforced concrete structures and timber structures.

An extension support member includes a bracket or web having a first planar portion or leg, a second planar portion or leg, an acute, concave angle between the first planar portion or leg and the second planar portion or leg, and a bend or backbone joining the first planar portion or leg to the second planar portion or leg. The extension support member also includes is a first mounting portion or tab joined to the second planar portion or leg via the bend or backbone at a first, convex obtuse angle and a second mounting portion or tab joined to the first planar portion or leg via the bend or backbone at a second obtuse, convex angle. The first mounting portion and the second mounting portion are located at opposite ends of the bracket or web.

In one embodiment, a modular assembly shelter kit is provided for rapid deployment in a remote location. The shelter kit includes headers, footers, upper horizontal beams, lower horizontal beams, roof, floor, and wall panels, and vertical support columns. The horizontal beams have notched hooks which form cross joints when engaged with notched hooks of adjacent horizontal beams. The cross joints can be placed against the headers or footers, and caged into position by prongs of the vertical support columns. The horizontal beams can also include grooves for holding interior and exterior wall panels, and interior ledges for holding roof and floor panels. Unique geometrically designed components deployed military or humanitarian responders with the ability to quickly manufacture and install such shelters in a wide variety of environments.

A framework section having a connection region which is formed on the end face of at least one of its two ends. The connection region can be connected to the connection region of a further framework section. The framework section can include two upper chord sections and two lower chord sections, which extend parallel to one another in the longitudinal direction of the framework section and are connected to one another by connecting struts such that they define a cuboid space. The upper chord sections and the lower chord sections can have a tubular cross section, wherein the upper chord sections and the lower chord sections can also be configured to transition from the tubular cross section into an I-shaped cross section in the connection region.

A plenum housing includes a plurality of construction panels and a plurality of compression seal groove connectors secured between the plurality of construction panels. Each of the plurality of compression seal groove connectors includes a recess having at least one interior surface with at least one compression seal groove.

A construction panel includes a concrete layer and a plurality of framing members coupled to the concrete layer. Each framing member includes first and second channels having respective webs and flanges extending from the webs to form openings in first and second channels facing away from each other. Each framing member also includes a plurality of flanges positioned in and extending across a gap between the first and second channels. Each framing member further includes at least one bent bar including a first plurality of bar sections, with each bar section of the first plurality of bar sections positioned adjacent to at least one flange of the plurality of flanges and extending out from within the gap and into the concrete layer.

A building structure assembly includes standardized interlocking components sized to suit any particular size of building required and ISO standard shipping containers, including: at least one modular base structure, at least one modular beam structure, and at least one wall support in the form of a shipping container and a method of assembly of the building structure. Each modular beam and base structures a frame, interlocking with each other and a shipping container by corner castings with twist lock assemblies, arranged in a particular orientation with each other. The modular base structure is supported by the corner castings of a shipping container and the base structure supports an end portion of at least one modular beam structure. A modular beam structure spans shipping containers. The modular beam structures can function as roof trusses and are sized to be transported inside shipping containers.

Disclosed is a gusset plate connection with sliding end plates for a buckling-restrained brace, including central plate (1), first rib plate (2), second rib plate (3), horizontal end plate (4), first horizontal tie plate (5), second horizontal tie plate (6), bolts (7) and unbonding layers (8). Horizontal end plate (4) is perpendicular to central plate (1) and fixedly disposed on a lower end surface of central plate (1). First horizontal tie plate (5) and second horizontal tie plate (6) are both disposed on an upper surface of horizontal end plate (4) and are located at two sides of central plate (1), respectively. Unbonding layers (8) are each disposed at a bottom surface of horizontal end plate (4), between horizontal end plate (4) and first horizontal tie plate (5), and between horizontal end plate (4) and second horizontal tie plate (6). The components are connected by means of bolts (7).

A column and beam connection structure for connecting a steel H-beam to a column uses an external diaphragm. The external diaphragm includes a plurality of divided diaphragm segments such that each diaphragm segment has a column plate abutting on the column. A diaphragm segment which is arranged along the steel H-beam among the plurality of divided diaphragm segments has a beam plate installed in a flange of the steel H-beam. The beam plate has an end portion in which the column plate is provided. A joining surface between the diaphragm segments is placed in a vicinity of a corner portion of the column so that only the column plate of one of the diaphragm segments abuts on each column surface of the column. A joining member fastens to fix between the diaphragm segments such that contact pressure is applied from the column plates to the surface of the column.
