Publication number: 20100043316Abstract: An improved building structure and method for making steel frame buildings includes a beam-to-column or beams-to-column joint or connection which is most preferably shop fabricated (as opposed to on-site fabrication) and which offers a considerable savings in both steel requirements (i.e., material savings) and labor to make the joint connection. Also, because material utilization is improved in the connection, the new structure is more resistant to damage by seismic events (i.e., earthquake), by severe weather, and to damage from blast effects (i.e., terrorist attack or accident), than was the prior technology. The improved building structure also mitigates against progressive collapse of the building.Type: ApplicationFiled: August 21, 2008Publication date: February 25, 2010Inventor: Jesse E. Karns

Publication number: 20080092459Abstract: A seismic energy damping system with plural redundancy for a building or structure subject to seismic perturbation (i.e., deflection of the building structure) includes a distributed plurality of seismic energy dampers, and a plurality of rigid shear panels cooperating with the building structure via the seismic energy dampers. The plural shear panels and plural seismic energy dampers distribute seismic energy absorption and dissipation throughout the building structure to avoid stress concentrations, and to dissipate significant seismic energy, thus limiting the amplitude of deflections of the building structure during a seismic event.Type: ApplicationFiled: October 21, 2006Publication date: April 24, 2008Inventor: Said I.

Patent number: 7340864Abstract: Elastic support units are provided to at least one of upper and lower track rails of a seismic isolation guide. The elastic support units include two elastic supporters that are superposed one over the other in a vertical direction, Each elastic support unit includes an elastically deformable bed plate, two mutually parallel side portions, and side wall portions extending between each of the two parallel side portions and the bed plate raising a lower surface of the bed plate a prescribed height above lower surfaces of the side portions and creating a space between the side wall portions. The elastic supporters are arranged in a vertically opposite relation with respect to each other positioning the respective bed plates at vertically opposite ends with the respective side wall portions being disposed orthogonal to each other. The track rails are secured to the bed plates parallel to the side wall portions.Type: GrantFiled: December 18, 2003Date of Patent: March 11, 2008Inventor: Hiroshi Teramachi

Patent number: 7337586Abstract: An anti-seismic device is adapted to absorb the vibration energy of a structure, and comprises a plurality of vibration-reducing units, each of which includes a mass, a hydraulic cylinder, and a resilient element. The hydraulic cylinder has an outer end that is connected fixedly to the structure, and an inner end that is connected fixedly to the mass. The resilient element has an outer end that is connected to the structure, and an inner end that is connected to the mass. When the structure is subjected to vibration, the masses can move reciprocally relative to the structure at different vibration frequencies. The hydraulic cylinders are arranged substantially in parallel.Type: GrantFiled: June 14, 2004Date of Patent: March 4, 2008Inventors: Chi-Chang Lin, Jer-Fu Wang

Patent number: 7338035Abstract: A shock suppressor has at least two sliding units stacked in an alternate manner, and each sliding unit consists of a moving base, a connecting base and at least one rod. The connecting base is moveably combined with the moving base via the at least one rod. At least one positioning hole and at least one curved guiding channel are defined respectively in the connecting base and moving base for the at least one rod to be mounted respectively in the at least one positioning hole and to extend moveably into a corresponding one of the at least one guiding channel. Accordingly, the shock suppressor can reduce or isolate the transmission of a shock efficiently.Type: GrantFiled: December 9, 2004Date of Patent: March 4, 2008Inventor: Chong-Shien Tsai

Patent number: 7325366Abstract: A seismic construction system for a cavity wall is disclosed. The system is shown in three exemplary applications—a masonry backup wall with ladder- or truss-type reinforcement cooperating with a snap-in wire tie; a masonry backup wall with ladder- or truss-type reinforcement with a high-span wall anchor cooperating with a low-profile, snap-in wire tie; and a drywall backup wall with internal insulation, a sheetmetal wall anchor, and snap-in wire ties. The snap-in wire ties accommodate a continuous reinforcing wire for the outer wythe, which reinforcing wire snaps into the wire housings therefor with a predetermined force. With the interconnected wall and veneer anchors and the respective reinforcing elements a seismic construct is formed.Type: GrantFiled: August 8, 2005Date of Patent: February 5, 2008Assignee: Hohmann & Barnard, Inc.Inventors: Ronald P. Hohmann, Jr., Ronald P. Hohmann
