A multi-story building includes a vertical support core that is disposed on a foundation, and a plurality of liftable floor plates. The liftable floor plates are fabricated at ground level and lifted into place on the vertical support core. The vertical support core includes vertically-oriented shear walls, and vertically-oriented columns disposed at corners thereof. Vertically-oriented first slots are formed between adjacent ones of the columns disposed at the corners. Each of the liftable floor plates includes girders, lateral framing members, diagonal framing members, and spandrels disposed at an outer periphery of the floor plate. The diagonal framing members are disposed diagonally in relation the lateral framing members and the first and second girders of the floor plate. The diagonal framing members extend through the first slots in the vertical support core and extend to one of the spandrels disposed at the outer periphery of the floor plate.

A building assembly system for fabricating a multi-story building is described, wherein the building includes a vertical support core arranged on a base. Lift jacks are arranged between a top portion and a bottom portion of the vertical support core, and a reusable bridle is suspended from the plurality of lift jacks and slidably arranged on the vertical support core. A floor plate is assembled onto the bridle at an assembly level that is proximal to the base. The plurality of the lift jacks are operable to lift the bridle and the assembled floor plate to a design elevation on the vertical support core, and are operable to lower the bridle to the assembly level on the vertical support core after the floor plate has been secured to the vertical support core at the design elevation.

Embodiments are directed to a lock for securing a structural assembly having a primary beam for constructing a core-supported high-rise building, and a building core wall defining an outer face. The lock includes a fixed bracket that couples to the primary beam of the structural assembly, a structural pin, a moveable component connected to the fixed bracket by the structural pin, and a recessed pocket embedded in the building core wall. The moveable component defines a bearing surface that contacts the outer face of the building core wall during the raising of the structural assembly. The recessed pocket receives the moveable component of the locking device when the structural assembly reaches one of the predetermined positions. The moveable component automatically engages with and disengages from the recessed pocket as the structural assembly rises, enabling temporary support and securement of the structural assembly at the predetermined positions during construction.

A method of constructing a building includes constructing a vertical support core of the building, and attaching a climbing rail to an exterior of the vertical support core. The climbing rail includes holes spaced vertically. A first floor plate is constructed around a periphery of the vertical support core, at a ground elevation, and includes at least one connecting rail having vertically spaced holes. A climbing jack is attached to the climbing rail, and moved vertically upward on the climbing rail to raise the first floor plate to a first floor final elevation. The first floor plate is permanently attached to the climbing rail at the first floor final elevation by inserting a pin through aligned holes in the connecting rail and the climbing rail.

Fabrication of a multi-story building includes fabricating floor plates at or near ground level, and lifting them to a final position on a vertical support core. A method for assembling one of the floor plates assembling a floor plate frame near ground level. Cambers are imparted into framing members based upon expected deflections, and metal decking is installed onto the floor plate frame. A plurality of permanent support points for the floor plate are determined, wherein the floor plate is attachable to the vertical support core at the permanent support points. First pedestals are installed between ground level and the floor plate frame proximal to the permanent support points for the floor plate. Hardenable material is dispersed onto the metal decking of the floor plate frame while the floor plate frame is lifted at the permanent support points.

A method of constructing a building includes attaching a first portion of a roof structure to the yokes of a vertical slip form system. A derrick crane is positioned on top of the first portion of the roof structure. A vertical support core of the building is then formed with the vertical slip form system. The first portion of the roof structure and the derrick crane are raised with the vertical slip form system. The vertical slip form system is removed from the formed vertical support core of the building, and the first portion of the roof structure is then moved into a final position and attached to the vertical support core. The remainder of the roof structure and subsequent floor plates may then be constructed at ground elevation, raised into place, and attached to the vertical support core in a top-down, descending order.
