    Abstract: A portal frame 3 made of wide flange sections without braces is fixed to the external surfaces of an existing RC-column 5 extending in the vertical direction and to the external surfaces of existing RC-beam 8 extending in the horizontal direction of a reinforced concrete building. The wide flange section column 4 fixed to the existing RC-column 5 is assigned a bending rigidity roughly equivalent to that of the existing RC-column 5, thereby reducing the stress additionally occurring at the connecting part between the existing RC-column 5 and column 4 by deforming the column 4 similarly to the existing RC-column 5 under the horizontal load transmitted from existing RC-beam 8 and/or wide flange section beam 6 during an earthquake. Using a steel portal frame without braces preserves the building appearance and avoids bracing which may block windows while increasing earthquake resistance.

  • Publication number: 20040221520
    Abstract: An all-directional damping and earthquake-resisting unit is fixed to a lower part of an object, such as a column of a building, and a foundation for the object, so that functionally different members of the unit normally bear the weight of the object. When there is an earthquake, round balls included in the unit automatically roll and rotate on ball restoring means provided on two ball carriers while a piston assembly automatically moves in a buffer space, so that an instantaneous impact by the earthquake energy and any earthquake-induced displacement are absorbed by the unit. The balls and the piston assembly finally automatically return to their original positions in the unit, enabling the object and the foundation thereof to always locate at the same place without the risk of deviating from their centers.

    Abstract: The invention is a damper and a method for protecting buildings and similar structural systems from dynamic loading such as loading caused by earthquakes, strong winds or machine vibrations. More specifically, the damper is made from structural members being interconnected in frictional or visco-elastically dampened rotational joints. Due to the dampening of the joints, relative movement between the structural elements is dampened. In particular, the damper is useful for base isolation, e.g., in order to allow a building or a machine to move in a dampened movement relative to its foundation or in order to allow a cable stay of a cable stay bridge to move in a dampened movement relative to its fixation point on the bridge.

    Abstract: An energy absorbing seismic brace for both retrofit and new construction. The brace comprises a central strut of either multi-legged or homogeneous section fabricated from low strength aluminum, whose characteristics maximize the seismic energy absorption for a building installation. This central strut absorbs energy at high weight-specific levels by virtue of the hysteresis in its load-deflection relationship. In order to eliminate the possibility of buckling of the energy absorbing strut when it passes through the compression portion of a load cycle, it is surrounded by a system of spacers and an external sleeve providing very high bending rigidity at low weight. The spacers may be fabricated from low-density foams, pseudo-concrete, fibrous composites, or metals, depending upon the application. The outer sleeve may also be fabricated from a variety of materials, depending upon whether the embodiment calls for the principal bending rigidity to be provided by the spacers or sleeve.

  • Publication number: 20040003548
    Abstract: An improved framed structure incorporating a coupled-girder system provides enhanced seismic energy dissipation by as much as 30% over that provided by conventional yielding of the girders. The coupled-girder system includes a pair of spaced-apart girders coupled by one or more girder-to-girder links which are preferably vertical links. Energy dissipation takes place when the structure drifts beyond its elastic limit and the differential displacement of the pair of girders causes the web of each vertical link to shear yield. The links are proportioned to remain in the elastic regime under wind loads and moderate earthquakes as prescribed by building codes. Beyond the elastic limit, preferably the yielding in the links will take place prior to that in the girders. In this way, the links will be the first line of defense for dissipating seismic energy before the girders themselves.

A mounting part of the closure arrangement is received in a space between two countersupport surfaces formed by a U-channel or opposite L-members that protrude perpendicularly from the sill or jamb surface of the wall bounding the opening. Mounting brackets secure the U-channel or L-members to the wall. On one or both sides, a respective damping element is interposed between the mounting part and the respective adjacent countersupport surface. The damping element may be a plastically deformable metal strip. When an explosion force acts on the closure arrangement, the damping element is first plastically deformed to absorb energy, before the remaining force is transmitted into the building wall. The two damping elements on opposite sides damp forces from the positive and negative pressure waves of the explosion.

  • Publication number: 20030159376
    Abstract: A window assembly (10) with its glazing frame that stays independently from lateral movement of building main structure (44) is disclosed. The window assembly includes an outer retaining frame (12) and an inner glazing frame (14). The retaining frame is attached to the building main structure. The glazing frame holds glass pane (20), and sits inside the retaining frame. Between the retaining frame and the glazing frame is a predetermined clearance space (X) and (Y), at their vertical edges and their top edge. The resulting window assembly allows the glazing frame to stay in its shape, while the retaining frame moves laterally with the main structure during earthquakes or blasts, thereby minimizing the chance of glass breakage. Application of glazing gasket (32) or sealant (54) provides watertight result to the window assembly.

  • Patent number: 6598365
    Abstract: An impact and energy absorbing product for floors, walls, panels, crash mats and other flat surfaces. More particularly, the invention teaches the usage of coiled springs in conjunction with polymeric materials or metals such as titanium or steel, to help absorb and dissipate forces of humans and other objects coming in contact with said flat surfaces. Depending upon the exact environment in which the same are to be used, the coiled springs may be constructed of polymers or metals such as titanium or steel—lightweight, yet durable materials to accomplish the purposes of the invention. In the preferred mode of attachment, an insert is fitted to each end of each spring, with a flared insert then placed into a molded female slot upon a flat surface to hold the spring in place. Thus, a floor or wall surface may comprise a series of female slots such that multiple springs can easily slide therein.
