A self-bearing curtain wall system is provided, the system including a matrix of unitized kinematically integrated cladding panels flexibly joined to a structural member so as to thereby responsively anchor said matrix of unitized cladding panels. Adjacent cladding panels of the matrix of unitized cladding panels are responsively linked horizontally and vertically for horizontal and vertical rotation. Horizontally adjacent cladding panels of the matrix of unitized cladding panels are responsively joined to a cable type structural member via an anchor fixture, which allows the structural member to move freely along the wall.

The present invention relates to an apparatus that will dampen vibration and sound created by heavy machinery, such as metal presses, metal stampers, and HVAC units, as well as limit lateral movement of the heavy machinery based upon a combination of a multiplicity of air springs and rigid cylinders. The present invention provides the simplest method of dampening vibrations and sounds created by heavy machinery. The present invention further prevents lateral movement of the machinery, while simultaneously providing a means to protect such machinery against seismic events by absorbing the seismic forces.

An improvement in the structure of an anti-shock device utilized for buildings, important structures and bridge structures that are made of a base, a carrier, a slide block, and a plurality of springs. A slip concavity of a sunken round curved recess is respectively formed in the base top surface and in the carrier bottom surface, and an upper slide block member and a lower slide block member are situated between the two slip concavities. One contact surface between the two slide block members and slip concavities is of a curved contour and the other surfaces are indented seating recesses. A spheroid coupling bearing is nested between the two seating recesses and the upper and lower slide block members are held together by the springs. As so assembled, the anti-shock device base is fastened under the columns of a building structure such that the building achieves the objectives of exceptional shock eliminating capability and greater building structure safety.

A method and apparatus for positioning mild steel reinforcing bars within a precast, moment resisting frame of a building. The apparatus includes a hand-receiving access component that can be installed within the concrete beams that make up the building frame so as to permit convenient access to the reinforcing bars that are slidably carried within bar receiving passageways formed within the concrete beams. Additionally, the apparatus includes a bladder-receiving component that can be installed within the concrete beams that make up the building frame in a manner to permit an expandable bladder to be conveniently positioned within the cable receiving passageways formed in the beam. When in position within a cable-receiving passageway, the expandable bladder spans the interface between the beam and the column and effectively prevents grout from entering the cable passageway during the grouting step. The apparatus also includes a novel joint sealing apparatus for sealing the peripheral portions of the joint formed between the columns and beams that make up the moment resisting frame.

An energy dissipation apparatus for installation in structural frames to mitigate seismic effects comprises a scissor-jack system of braces with an energy dissipation device such as a viscous, viscoelastic, or hysteretic damper, or an active or semi-active device, connected between opposing pivot joints of the scissor-scissor jack system. The scissor jack system magnifies displacement so that energy is dissipated more effectively by the damper. Open bay, diagonal, and alternative installation arrangements with respect a structural frame are disclosed.

In a structure for installing a viscous vibration-damping wall, high-strength bolt hole portions are provided for connecting a lower-floor girder and a base plate forming part of the wall. Gusset plates are disposed on both sides of the group of the high-strength bolt hole portions. A pair of flange plates are respectively provided with a pair of gusset plates. High-strength bolt hole portions and a pair of gusset plates for connection to opposing gusset plates are embedded in a flange of the lower-floor girder, to connect the viscous vibration-damping wall and the lower-floor girder. The viscous vibration-damping wall is connected to an upper-floor girder by directly connecting a gusset plate fixed to the upper-floor girder and an intermediate plate of the viscous vibration-damping wall.

The seismic isolation sliding support bearing system includes a pair of sliding bearings, which can be moved relatively to each other and are arranged in opposition and in contact with each other between a superstructure and a substructure. At least one of the pair of sliding bearings is a sliding bearing (a) made from a molding, having a porous structure including a plurality of voids, of a composition including PTFE as a main component and aromatic polyester resin, or a composite including a base member having the molding on the surface thereof. Furthermore, a lubricant holding layer for holding a flow lubricant in the voids is formed in a surface portion of the molding. Since the sliding bearing (a) has a high compression elastic modulus (of 900 MPa or more) and a low coefficient of friction (of 0.02 or less) and can maintain the low friction for a long period of time, it can be particularly effectively used in a seismic isolation sliding bearing support system for structures with a large load.
