Abstract: 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.

Abstract: 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.

Abstract: A building that includes a lower structural pad disposed on a foundation is described, and includes columns disposed on the lower structural pad, including a first of the columns being separated from a second of the columns by a first span. The building includes a plurality of horizontally-oriented reinforced transfer beams, wherein each of the reinforced transfer beams spans between the first of the columns and the second of the columns. The building includes a vertical support core including a first vertically-oriented structural spine and a second vertically-oriented structural spine that are disposed on the reinforced transfer beams and separated by a second span. The second span associated with the first and second vertically-oriented structural spine is less than the first span associated with the first and second of the columns. Each of the reinforced transfer beams includes a steel beam and a carbon-fiber reinforcement element.
