    摘要: A modular energy-dissipating fabricated structure for a transmission tower includes a base, two T-shaped beams, a vibration damping mechanism, a connection plate, and four supporting beams. The vibration damping mechanism slides to generate the damping force and energy dissipation. The larger the displacement of the vibration damping mechanism, the greater the damping force provided by the system. This effectively reduces vibration of an upper structure of the transmission tower, and lowers a probability of damaging the upper structure in a natural disaster. The modular energy-dissipating fabricated structure realizes hierarchical control under different loads. Under an action of a dynamic load such as a strong wind, a small sliding range of the vibration damping mechanism can realize vibration damping and energy dissipation purposes of the structure. When a strong dynamic load such as an earthquake is applied to the structure, the vibration damping mechanism reduces an impact on the structure.

    摘要: A shear wall assembly is provided. The assembly includes a first anchor, a second anchor, a third anchor, a first bolt, a second bolt, a seismic fuse, and a rod. Each anchor includes a hollow tubular body including a first open end, a second open end, an interior including female threads, and an exterior including male threads. Each bolt includes a head and a shank. The shank includes male threads. The shank extends through an open end of an anchor. The male threads of the bolt engage with the female threads of the anchor. The seismic fuse is configured to receive the heads of the bolts and includes a hole. The rod includes an end with male threads. The rod extends through the hole of the seismic fuse into the open end of an anchor. The male threads of the rod engage with the female threads an anchor.

    摘要: A passive damper for damping relative lateral movement between a tensioned cable or other oblong member and a support structure includes a first fixture element rigidly connected to the cable or other oblong member, a second fixture element rigidly connected to the support structure, and at least one rotational damping device arranged between the first and second fixture elements . The rotational damping device is configured to translate the relative lateral movement into relative rotational moment between at least two arms of the rotational damping device that are connected at a rotational joint with a damping pad clamped in between the at least two arms The rotational joint has a rotational axis (Y) substantially parallel with a longitudinal axis (X) of the cable.

    摘要: An attachment device for securing a non-structural component of a building to a structural component of the building includes a non-structural component holder defining a receiving space configured to receive the non-structural component to couple the non-structural component to the attachment device. The non-structural component holder applies generally no compressive force against the non-structural component when the non-structural component is disposed in the receiving space so that the non-structural component is free to move relative to the non-structural component holder. A stop is configured to be secured to the non-structural component. The stop is configured to engage the non-structural component holder to inhibit movement of the non-structural component relative to the non-structural component holder when the stop and non-structural component holder are secured to the non-structural component.

    摘要: A structure having limited supportable portions has been difficult to isolate from vibration in the direction in which a load is applied. A base isolation apparatus includes a Z-axis base isolation unit, an X-axis base isolation unit, and a Y-axis base isolation unit. The base isolation unit includes a vibration-source connector, an isolated-object connector, a lock device disposed between the isolated-object connector and the vibration-source connector for switching between a state of fixing the isolated-object connector and a state of making it movable, a distance recovery device for generating a force to cause an amount of change in distance to approach zero, depending on the amount of change, and a vibration damper for generating a force in an orientation of hindering the change, depending on the rate of change in distance.

    摘要: A shearwall is disclosed for use in lightweight or other constructions to transmit lateral shear forces and dissipate energy on the construction. In examples, the shearwall includes a central panel formed of wood, and side plates formed of steel. The side plates may be affixed at lower corners of first and second opposed surfaces of the central panel. Each side plate may include a fastening plate for affixing the side plate to the central panel, and a restraint plate which fits within a reduced area section of the central panel between the first and second surfaces.
