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.

Abstract: 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.

Abstract: A strut may be interposed between a first floor plate and a second floor plate of a multi-story building, wherein the first floor plate is disposed overtop of the second floor plate. The strut includes a first post section and a second post section. The first post section includes a first portion that is coaxial with, annular to and slidably disposed within a second portion of the second post section. A damping actuator is interposed between the first post section and the second post section, and is arranged to dynamically control a position of the first post section in relation to the second post section. The strut also includes an accelerometer. A controller is in communication with the accelerometer and the damping actuator, and controls the damping actuator to control the position of the first post section in relation to the second post section.

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.

The assembly pad includes a top surface disposed at a ground level elevation of the building, and covers a footprint of the building. A plurality of tie-downs are attached to the assembly pad. A plurality of jack pedestals is positioned on the assembly pad, and are operable to support the floor plate, and raise and lower the floor plate relative to the assembly pad. Camber may be introduced into selective frame members by restraining the frame member to the tie-downs and extending a respective jack pedestal. The floor plates may be raised in their entirety to a work height with the jack pedestals to allow workers easy access to an underside of the plate.
