The bearings are adapted to minimize friction between the core member and the buckling restraining apparatus. An air gap is positioned between the core member and the one or more bearings of the buckling restraining apparatus are adapted to prevent bonding of the core member and buckling restraining assembly. Projections are included in the core member of the brace apparatus to minimize movement of the middle portion of the core member relative to the buckling restraining assembly.Type: GrantFiled: May 11, 2004Date of Patent: May 18, 2010Assignee: SME Steel Contractors, Inc.Inventor: James M. Smelser

Patent number: 7712266Abstract: A pin-fuse frame is used in a frame assembly that may be subject to extreme seismic loading. The pin-fuse frame includes of columns, beams, plate assemblies that extend between columns and beams, and may included a diagonal brace. The plate assemblies are fixed to the columns and attached to the beams and brace via pin joints. A joint includes a pin connection through outer connection plates connected to a column and inner connection plates connected to a beam. Connecting rods positioned about the pin maintain a coefficient of friction until exposed to extreme seismic activity, at which time the joint accommodates a slippage of at least one of the inner and outer connection plates relative to each other rotationally about the pin. The diagonal brace is separated into two segments connected together with connection plates. These connection plates accommodate a slippage of the segments relative to each other.Type: GrantFiled: May 22, 2007Date of Patent: May 11, 2010Assignee: Skidmore Owings & Merrill LLPInventor: Mark P. Sarkisian

Publication number: 20100107518Abstract: A seismic bracing assembly has a first subassembly and a second subassembly that are connected by a sleeve. The first subassembly has a structural yoke used to secure the first subassembly to a structural member. The second subassembly has another yoke used to secure the second subassembly to an anchoring member. The first and second subassembly have a sufficient length to allow rough in assembly of the two subassemblies with the sleeve that couples them together.Type: ApplicationFiled: October 30, 2009Publication date: May 6, 2010Applicant: NIBCO, INC.Inventor: Richard W.

Patent number: 7707788Abstract: A buckling restrained brace includes a deformable core contained within an outer casing. Ends of the core protrude from the casing for connection to a frame or other structure. A length of the deformable core between its ends, referred to as the gauge or yielding section, is capable of deforming during an earthquake or blast loading. The gauge section is differentially heat treated from the ends so that the gauge section has a lower yield strength than the ends. The casing provides containment of the core to prevent buckling of the core. A metal foil interface or unbonding layer is provided between the deformable core and the casing so that the deformable core does not bind to the casing. The buckling restrained brace provides significant performance improvements over prior art BRBs coupled with simplified assembly.Type: GrantFiled: March 19, 2007Date of Patent: May 4, 2010Assignee: Kazak Composites, IncorporatedInventors: Pavel Bystricky, Jerome P. Fanucci

Patent number: 7703244Abstract: A joint structure includes a splice plate and a gusset plate, which can prevent out-of-plane buckling of the gusset plate without the necessity of welding a stiffening rib plate thereon. The joint structure includes a gusset plate and at least one splice plate connected to the gusset plate. Each of the splice plates is constructed from section steel having a non-rectangular cross-section. The joint structure can be used in a building during assembly of the building or for reinforcement of the building.Type: GrantFiled: April 22, 2004Date of Patent: April 27, 2010Assignee: Nippon Steel CorporationInventors: Kazuaki Suzuki, Yasushi Maeda, Tooru Takeuchi

Publication number: 20100058681Abstract: A hold down connector is provided for securing together multiple building members. The hold down connector resists movement of the building members when connected to an elongated tie member. In one embodiment, the hold down connector includes a transverse portion connected to first and second elongated legs with at least one aperture at elongated connections between the transverse portion and the first leg and between the transverse portion and second leg. In another embodiment, the hold down connector includes a transverse portion connected to first and second elongated legs with the transverse portion partially supported by transverse extensions of the first and second legs. A hold down connector in accordance with embodiments results in increased load bearing properties, construction from thicker materials, and easy installation.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Applicant: TRUSSED, INC.Inventors: Robert D. Lucey, Ronald F. Nelson

Patent number: 7654043Abstract: The invention relates to a retrofit connector for fast attachment to an existing system that supports a suspended load below a ceiling, beam or floor without the need to disassemble or disconnect any components of the system. Advantageously, the connector is easy to install and inexpensive to manufacture. The connector is removably or permanently attachable to a sway brace clamp or attachment to form a pivotable connector-clamp assembly. The assembly is capable of reliably supporting heavy loads against adverse sway and seismic disturbances.Type: GrantFiled: July 30, 2004Date of Patent: February 2, 2010Assignee: Nibco Inc.Inventor: Richard W. Heath

Publication number: 20100018134Abstract: A shock-absorbing tie brace has a central member and an outer frame. The central member has two ends and multiple neck portions. Each neck portion has a dimension of cross section smaller than that of the ends to form multiple enlarged portions beside the neck portions on the central member. The outer frame is mounted around and encloses the central member. Accordingly, the shock-absorbing tie brace has an excellent capability for bearing buckling load and is not easily bent or buckled.Type: ApplicationFiled: October 2, 2009Publication date: January 28, 2010Inventor: Chong-Shien Tsai

Patent number: 7647733Abstract: A reinforcing structure for a building and a reinforcing member used for the structure, where the structure has excellent anti-vibration characteristics and quake resistance. The reinforcing structure and member for a building are capable of reducing the deformation of structural members of the building caused by vibration and removing the deformation so that the original form is restored. A reinforcing member (1) is provided and fixed at a corner portion where structural members (11, 12) of a building intersect. The reinforcing member (1) is formed such that a first spring member (third leaf 33) and a second spring member (layered leaf (5)) are combined, and a damper (4) and a synthetic resin foam body (2a) are arranged in a space between the first and second spring members. A synthetic resin foam body (2b) is filled in a space surrounded by the structural members (11, 12) and the reinforcing member (1).Type: GrantFiled: December 2, 2003Date of Patent: January 19, 2010Assignee: Nakamura Bussan Co., Ltd.Inventors: Takuzo Nakamura, Kiyotaka Nanama, Takaaki Eguchi
