The present invention provides a cross beam of a canopy, which addresses the problem that existing cross beams cannot simultaneously ensure convenience of assembly and guarantee stability in use. The present cross beam of a canopy comprises a plurality of hollow elongated beams, an inner side surface of each of the beams has at least one protruding and elongated protrusion along a length direction of the beams, each of the protrusions is provided with an mounting hole or a mounting groove penetrating along the length direction of the beams, at least one long rod is inserted into the mounting holes or the mounting grooves to connect all the beams in series, and two ends of the long rod protrude out of the beams and are detachably connected with a locking fastener respectively. The present invention ensures convenience of installation and guarantees the assembled cross beam has good stability.

A building system that includes a modular panel with side members, at least one of the side members having an associated coupling for hooked connection with a corresponding shaped fixture of an adjacent structure, the coupling and fixture being adapted to be held together by a locking device that, when engaged, acts to lock the structure and the side member together and, when disengaged, allows for play between the panel and structure in order to free the panel from the structure.

A cutout part is formed at the approximate center of the connecting member. The cutout part in the connecting member is a circular penetrating hole that penetrates a convex part and a main body part. On the side of a lower surface of the connecting member, the convex part is formed around the cutout part. The convex part includes a tapered part and a rib. The tapered part gradually inclines in the direction toward the center from the side of the main body part (the side of the base part of the convex part) to the tip side (the side of the top part thereof). The rib part is formed on the edge part of the cutout part, which is the top part of the tapered part. The rib part is a part that protrudes downward from the top part of the tapered part.

A method and an arrangement for supporting a first beam between a first support structure and a second support structure in a building frame structure. The method includes securing the first beam to a first console against movement along the first console by means of a mechanical joint between the first console and the first beam, and the first console at a location between the beam supporting surface of the first console and the mechanical joint with a deforming section having increased deformability compared to the deformability of the first console at the beam supporting surface by reduced material dimensions in said deforming section of the first console compared to the material dimensions of the first console at the beam supporting surface.

A connector for coupling a first column segment having a first inner surface and a first end surface to a second column segment having a second inner surface and a second end surface such that the end surfaces are adjacent one another is provided. The connector includes a plurality of fasteners and a plurality of plates each having a front face, a rear face, and a plurality of fastener apertures extending from the front face toward the rear face. Each of the fastener apertures is sized to receive one of the fasteners when coupling the first column segment to the second column segment such that the plates are spaced apart from one another. Each of the front faces is contoured to seat flush against the first inner surface and the second inner surface when the plates span the adjacent end surfaces of the coupled-together column segments.

A system and method for construction of a framed structure which permits on-site storage and relocation of construction materials using trolleys and cranes supported by the framed structure. The system provides a runway surface for removable attachment of trolleys, crane bridges, and platforms by offsetting the first longitudinal beam and a second longitudinal beam from a cross beam and where the first longitudinal beam, second longitudinal beam, and cross beam of the system provide components for the framed structure.

A connector is provided. The connector includes a flange defining an opening. The connector also includes an insert having a plurality of plates. Each of the plates extends through the opening of the flange. The connector further includes an actuator coupling the insert to the flange. The plurality of plates are movable relative to the flange by operating the actuator.

Various embodiments disclosed herein relate to moment-resisting frames, kits for assembling such moment-resisting frames, and methods of repairing such moment-resisting frames. In an embodiment, a moment-resisting frame includes a beam connected to a column using a moment-resisting connection. The moment-resisting connection may include at least one exterior doubler plate (“EDP”) that is connected to the column and two or more connectors that are connected to both the beam and the EDP. In some embodiments, the moment-resisting frame may require less welding than conventional beam-to-column connections. Additionally or alternatively, such a moment-resisting frame may eliminate the need for components typically used in conventional beam-to-column connections (e.g., continuity plates).

A gusset plate assembly for use in connecting at least two beams to a hollow tubular column in a building. The gusset plate assembly can receive said at least two beams in a biaxial orientation of said beams. The gusset plate assembly comprises gusset plates sized for transferring the weights of said at least two beams and their reaction forces and bending moments from the application of severe load conditions acting on the building to the hollow tubular column. At least one of the gusset plates receives a portion of a second of the gusset plates. A joint penetration groove weld joining the first and second gusset plates together allows the gusset plate assembly to be free of welds on its internal corners. A method of assembling a gusset plate assembly is also disclosed.

A structural yielding link, particularly for use in an eccentrically braced frame arrangement or in a linked column frame arrangement having a first end having a means for connecting to a face of a first beam and a second end having a means for connecting to a face of a second beam; a first variable cross-section portion and a second variable cross-section portion extending from the first end and from the second end, respectively; and a constant cross-section portion joining the first variable cross-section portion and the second variable cross-section portion.
