A module for a structural system may include chords oriented along a length of the module and a plurality of rib assemblies positioned between the chords. Two of the rib assemblies may include shear keys configured to be received in piers at a final installation site. A method of making a structure may include positioning the shear keys in pockets of the piers.

Various implementations described herein are directed to a load bearing ledger fitting, a modular header beam, a perimeter safety deck, a multi-purpose bearing plate, and a mega-shore bearing plate of an integrated construction system.

A ductile anchor attachment (DAA) mechanism is disclosed. Example embodiments are directed to a DAA fuse plate including a bottom section configured to connect to an existing anchor; a tapered lower section; a narrowed neck forming a ductile yield mechanism; a tapered upper section; and a connection mechanism for direct removable coupling of the DAA fuse plate to a structure being anchored, the connection mechanism being in contact with the tapered upper section of the DAA fuse plate, the DAA fuse plate in combination with the connection mechanism being configured to not buckle under compression forces and to adjustably dissipate tension forces acting on the structure being anchored.

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.

Embodiments are directed to structural fuses and connection systems including the same. An example structural fuse includes at least one plate. The structural fuse includes a plurality of cutouts formed in the plate. The cutouts are configured to cause at least one first yield region of the plate to yield when a first load is applied to the plate. Optionally, the plurality of cutouts are configured to cause at least one second yield region to yield when a second load is applied to the plate. At least a portion of the first yield region is distinct from at least a portion of the second yield region and the first load is different than the second load.

Embodiments are directed to base connections, structures including base connections, kits for forming the base connections and/or structures, and method of repairing yielded base connections. In an embodiment, a base connection includes a base plate including a top surface and a bottom surface opposite the top surface. The top surface is configured to be adjacent to a terminal end of a column and the bottom surface adjacent to a foundation. The connection also includes one or more anchor rods attached to the base plate. The anchor rods are configured to secure the base plate to the foundation. The connection includes at least one structural fuse configured to be attached to the column and attached to the base plate. The fuse includes a plate with at least one cutout formed therein. The cutout is configured to form one or more yield regions that are configured to preferentially yield.

Exemplary embodiments relate to a quick-assemble construction system that includes various components that can be positioned and interconnected quickly and later adjusted and tightened. The quick-assemble construction system was envisioned specifically for freestanding seating systems that can be quickly installed and removed if needed, although the quick-assemble construction system can be used in a wider range of applications and is not limited to seating systems.

The present invention relates to a wind brace band connector comprising at least a first and a second one-piece connector element for connecting at least one perforated band defining a longitudinal band axis to a connection bracket attached to a building, or for connecting at least two perforated bands with each other. The connector is easy to connect to a perforated band, i.e. a wind brace strap using no or just a simple tool.

A connection assembly for modular construction includes an upper junction connector coupled to an upper end of a column. The upper junction connector includes an upper end that has a planar upper surface, a recessed surface, and at least one connector sidewall extending between the upper surface and the recessed surface. The recessed surface and the at least one connector sidewall define a contiguous recessed area in the upper end that extends to second, third, and fourth edges of the upper end of the connector. A slot extends through the upper end adjacent to an interior surface of a column sidewall. A transverse bore extends through the first column sidewall proximate to and aligned with the slot.

Column-to-beam connection systems are disclosed herein, along with moment-resisting frames including the same and methods of repairing the same. An example column-to-beam connection system includes a shear component. The shear component includes abase plate that is connected to a column flange. The shear component also includes at least one vertical web extending from the base plate. The vertical web is connected to with a beam flange. The vertical web also defines one or more openings therein.
