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 structural assembly (10) comprising a first structural member (100), a second structural member (200), and a lock plate (300). Each of the structural members (100, 200) have a first portion (102, 202) which extends in a first plane and a second portion (103, 203) which extends away from the first portion (102, 202) and which extends in a second plane at an angle to the first plane. The first portion (102, 202) of the structural members (100, 200) are provided with an engagement feature (104, 204) configured to interlock with a compatible engagement feature (304) provided on the lock plate (300) of the structural assembly. The second portion (103, 203) of the first structural member (100) and second structural member (200) being provided with: compatible seating features (106, 206) configured to seat one of the structural members (200) on the other structural member (100).

A construction formed of column and a beam, where the beam has top and bottom flanges coupled to the column by a lateral bracing system, and a web between the top and bottom flanges. The lateral bracing system may include a column-mounted plate including a horizontal portion and a vertical portion, the vertical portion affixed to the column. The beam may be coped at top and bottom edges of the web to prevent binding of the beam flange with the column-mounted plate upon rotation of the beam relative to the column.

A lateral bracing system is disclosed for affixing a column to a beam in a construction. The lateral bracing system includes a pair of buckling restraint plates, one each affixed to a top and bottom flange of a beam. The lateral bracing system further includes at least one yield plate for each buckling restraint plate. Each yield plate includes a first end affixed to the column, and a second end affixed to the beam.

A joint connection structure of a building framework includes a column assembly including a column and a pair of gusset plates connected to the column on opposite sides of the column and extending laterally outward from the column. A full-length beams assembly includes a full-length beam having upper and lower flanges and an end portion received between the gusset plates. A connecting member is operatively attached by welding to at least one of the flanges of the full-length beam. The connecting member is bolted to at least one of the gusset plates of the column assembly to connect the full-length beam assembly to the column assembly.

Disclosed herewith a modular integrated building and a construction method thereof. The building comprises multiple prefabricated room units (1). A bottom of a load-bearing structure of the prefabricated room unit (1) is provided with a semi-prefabricated connecting port (2). Reinforcing bars arranged at a top of the prefabricated room unit (1) of a next floor are inserted in the connecting port (2) and thus connected with reinforcing bars arranged therein, so that the prefabricated room units (1) of two adjacent floors are connected with each other through in-situ casting concrete in the connecting port (2). A cast-in-situ concrete interlayer (3) is arranged on a top plate (11) of the prefabricated room unit (1) of a next floor, for connecting adjacent prefabricated room units (1) of a same floor together.

A positioning device and method for producing a construction material body. The positioning device holds and orients a reinforcement body consisting of a textile reinforcement within a formwork. The positioning device comprises first and second holding part groups arranged on a main body. At least one of the two holding part groups is movable between holding and release positions. In the holding position, each holding part acts on an associated location of engagement on the reinforcement body. In the release position, the distance between the holding parts is different from the distance between the locations of engagement on the reinforcement body, such that the positioning device is brought into engagement with the reinforcement body or can be removed therefrom. In the release position, independent handling of the positioning device relative to the reinforcement body is possible. To switch between the holding and release positions, an actuation device is provided.

A damped reinforced joint for a beam-column connection is provided for improving the resistance of steel-framed buildings against progressive collapse. Prestressing cables extend across each joint, and each prestressing cable is partially encased within a bent pipe. Each bent pipe may have multiple bends, forming a rippled or undulating shape. The prestressing cables strengthen the connections in the joints, and the bent pipes provide damping for dissipation of seismic energy and the like, thus improving resistance to earthquakes and other seismic, vibratory and/or shock events to the building frame.

The invention teaches a technology to control the load transfer from attachments into building structures and from building structures to attachments to protect building structures and attachments from damages beyond repair. The connector invented for this purpose acts as a fuse. It is inexpensive and easy to manufacture, install, and maintain.

A method of retrofitting a pre-Northridge type steel beam-to-column connection, includes welding the web of the beam to a flange of the column and slotting the beam web in the region of the connection and near the beam flanges. Stress relief holes are made into the web of the beam and slots are cut into the web of the beam. A top backup bar is welded to the flange of the column and a bottom backup bar is removed from the flange weld to the column. The method includes back gouging the flange of the column at a position of the removed backup bar and welding a bottom flange of the beam to the flange of the column.
