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.

In one aspect, a smart corner is provided that can be prefabricated. The smart corner comprises a rear side including a first hole, a first side including a second hole, a second side including a third hole, and a top. A wall frame is also provided. The wall frame includes a top plate, a bottom plate, studs, and four smart corners. A framing system is also provided comprising at least two wall frames. The at least two wall frames connect via the smart corners.

A reversible structural component for use as a portion of a vertical frame in a modular wall system includes an elongate body extending between a first end and a second end thereof, a plurality of countersunk through-holes extending through the structural component, and a plurality of threaded through-holes extending through the structural component. The countersunk through-holes and the threaded through-holes are disposed on the elongate body between the first end and the second end so that the countersunk through-holes of the structural component are aligned with the threaded through-holes of a separate identical structural component when back sides of the structural component and the separate identical structural component are brought together 180-degrees relative to one another during use.

A system for mounting a load to a wall frame is disclosed. The system has upper and lower mounting systems. Each of the upper and lower mounting systems has a wall bracket and a load bracket. The wall brackets of the upper and lower mounting systems each include a retaining flange, and are configured to be mounted to the wall frame. While the wall brackets of the upper and lower mounting systems are mounted to the wall frame, a space is defined between the wall and the retaining flanges. The wall bracket of the lower mounting system includes a ledge that is configured to support the load. The load brackets of the upper and lower mounting systems each include a retainable flange, and are configured to be mounted to the load. While the load is mounted to the wall, the weight of the load is supported by the ledge.

A building construction system comprising: a primary support member having a first end and a second end, an inner facing part and an opposite outer facing part, a secondary support member having a first end and a second end, inner facing part and an opposite outer facing part, a first beam having a first connecting part, a second connecting part, an inner facing part and an outer facing part, where the outer facing part of the first connecting part is configured to be attached to the inner facing part of the primary support member and an outer facing part of the second connecting part is configured to be attached to the inner facing part of the secondary support member, and where outer facing part of the first beam comprises a spacer element that is configured to extend from the primary support member to the secondary support member where an outer facing part of the spacer element is configured to be coextensive to the outer facing part of the primary support member and/or the outer facing part of the secondary support member.

An apparatus for adjusting a haunch height and related systems and methods includes a support angle. The support angle includes first and second flanges, and a surface of the first flange includes a hole. The apparatus also includes a coil rod and a rotatable nut.

A multi-story building that includes a vertical support core and a plurality of floor plates is described, wherein fabrication of the building includes, in one embodiment, assembling each of the floor plates at or near ground level, and lifting each of the floor plates to a design level on the vertical support core. A system and device for securing one of the floor plates to the building includes employing a vertically-oriented lock-in bracket.

A prefabricated column assembly includes a hollow tubular column having a longitudinal axis. A gusset plate assembly includes a plurality of gusset plates connected to the column and extending laterally outward from the column in planes generally parallel to the longitudinal axis of the column. A first pair of the gusset plates extends laterally outward from the column along a first axis and defines a space for receiving an end portion of a first beam for mounting the first beam on the first pair of gusset plates. A second pair of the gusset plates extends laterally outward from the column along a second axis that is nonparallel and non-coincident with the first axis. The second pair of gusset plates defines a space for receiving an end portion of a second beam for mounting the second beam on the second pair of gusset plates to provide a bi-axial joint connection.
