The reinforced joint for a beam-column connection is provided for improving the resistance of steel-framed buildings against progressive collapse. Flange stiffening plates reinforce flanges of structural beams, with beam web stiffeners being attached to and extending between the flange stiffening plates. Additional column web stiffeners are attached to and extend between flanges of a structural column. A longitudinal cover stiffening plate is attached to the column stiffeners and the flange stiffening plates, extending across the joint and at least partially covering the beam web stiffeners. The reinforced joint between the structural beams and the structural column develops catenary action in the structural beams in the event of collapse.

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 structural assembly (10) comprising a first structural member (100), a second structural member (200), and a lock plate (300). Each of the first structural member (100) and second structural member (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 first structural member (100) and second structural member (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 system for providing an angled construction or bent beam construction. Such system may include a first beam comprising a first elongated beam segment having a first interlocking joint portion at one end, and a second beam comprising a second elongated beam segment having a second interlocking joint at one end, wherein the first interlocking joint portion is configured to rotatably couple to the second interlocking joint to form a rotatable joint such that the angle between the first beam and the second beam is adjustable.

A framing system for constructing at least a portion of a building. The framing system comprising beams, cross beams, corner posts, and inline posts. The beams including flanges and a wall arranged between the flanges. The cross beams including a flange and a wall attached to the flange. The corner posts including walls and flanges. The inline posts including flanges and a wall arranged between the flanges. The flanges include slots and the walls include open areas. Panels may attach to the slots. Decorative patterns may be integrally formed in the open areas.

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.

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 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.

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.
