20100043317FRICTIONAL DAMPER FOR DAMPING MOVEMENT OF STRUCTURES - 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.02-25-2010
20100043316Steel-frame building and method of making - 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.02-25-2010

The reinforcing plate is compressed to double-layer or more, that is, multi-layer in due order, on the reinforced concrete column. Accordingly, since a workability of the retrofit is excellent and since the reinforcing plate is easily compressed on the surface of the reinforced concrete column by a small lateral pressure, sufficiently the reinforced concrete column could be reinforced. Besides, a compressive strength of the reinforced concrete column could be increased. In addition, the flexibility of the reinforcing plate and the energy absorption force of the reinforcing plate could be increased.07-02-2009
20130047523PASSIVE STRUCTURES WITH HIGH STIFFNESS AND HIGH DAMPING PROPERTIES - A passive structural system includes a structural element which may be subjected to energy which gives rise to vibration in the element. At least one bi-stable sub-structure is coupled to the element. Each bi-stable sub-structure has two stable equilibrium states between which the sub-structure can physically transition when subjected to a sufficient amount of energy which gives rise to vibration in the element, with each bi-stable sub-structure arranged to dissipate at least a portion of the energy and thereby damp the vibration in the structural element when it transitions from one equilibrium state to the other. The passive structural system may also be intentionally mistuned such that when subjected to energy which gives rise to vibration, the vibration energy is substantially confined to localized regions within the system. The bi-stable structures are then located in the localized regions and arranged to dissipate the localized vibration energy.02-28-2013

20100101160Method and Apparatus for Increasing the Energy Dissipation of Structural Elements - According to one embodiment, the energy dissipation of a structural element is increased by inserting one or more resisting elements into the structural element at any time during or after construction of the structural element. The continuous resisting elements are rigidly attached to the structural at one end and connected to the structural element by and through a damping material over at least a portion of its length. When a dynamic force is applied to the structural elements, such as may result from wind or earthquakes, there will be a strain in the structure, in a direction parallel with the longitudinal direction of the resisting elements. In this way, the forces and deformations within the structure will result in a relative motion between the structural element and resisting element, a substantial portion of which is ultimately transmitted by and through the damping material layer. In transmitting such a force and movement through the damping material layer, a portion of the energy associated with such force and movement is dissipated.04-29-2010

20130145703Seismological Engineering - The invention is directed to develop for the construction method for strong resistance to the earthquake according to new architecture rationale which all construction for building should be founded on the platform to be moved in alignment with the movement of the earthquake eliminating any piles to drive into the earth to adhere and building materials to combine each other firmly, by means of converting the vibration energy of the earthquake into the kinetic energy either to run idle the balls or to operate the up and down movement of the cylinder applied to the pile as the leg of the building rested on the ground in alignment with the movement of earthquake to deteriorate efficiency of transmissibility or to consume away for vibration energy of the earthquake as much as possible from an architectural point of view, it were just like idling operation as if car tires have sunk into sand.06-13-2013
20120017523METAL JOINT, DAMPING STRUCTURE, AND ARCHITECTURAL CONSTRUCTION - The invention provides a metal joint connecting a pair of subject members relatively displaceable in one direction, a metal joint connecting a pair of subject members relatively displaceable in one direction, the metal joint comprising: multiple first attachment portions attached to one of the subject members; a second attachment portion attached to an other of the subject members; and multiple plate portions connecting between the first attachment portions and the second attachment portion to each other, wherein an attachment direction of each of the first attachment portions with respect to one subject member and an attachment direction of the second attachment portion with respect to the other subject member are set so that a surfaces of the plate portions follow a direction of the relative displacement.01-26-2012
20130199112STRUCTURAL SHEARWALL - A shearwall adapted for use in a building or other structure includes a main concrete portion and structural reinforcement positioned within the main concrete portion. The shearwall is configured to resist lateral forces to which the building or other structure may be subjected. Further, the shearwall is configured to accommodate a vertical load such that the need for at least one separate structural column is eliminated.08-08-2013
20130205689CONNECTOR FOR SUSPENDED METAL CEILING FRAMEWORK AND CEILING EMPLOYING SAME - A connector for a ceiling framework including profile sections crossing one another at right angles for connecting the profile sections by being fitted to ends of certain profile sections which fit into apertures pierced in other profile sections. The connector includes two parts, a primary clip and a secondary clip, the two parts being associated with one another via a meltable mechanism capable of melting at a temperature of a fire to separate the two parts. In a fire, the secondary clips become detached allowing the primary clips to fit more deeply into the apertures of the profile sections, making it possible to absorb expansions due to heat of the fire and keep the framework and the ceiling sections it supports in place. The connector can be applied to the field of building construction, for example.08-15-2013
