摘要:
A plurality of laminated rubber or rubber-like elastoplastic ring-configured pads vertically stacked and secured together to provide seismic damping for a building structure. The laminated pads include ring-like steel plates or solid disk-like steel plates to form one laminated stage of a multi-stage seismic damping device. A plurality of damping devices are used to support a vibratable mass on a building structure. The combination of stacked ring-configured elastoplastic pads and steel plates provides a damping device having a high lateral deformation capacity with a long period and high resistance to buckling. The damping device is suitable for protecting building structures having long natural periods, such as multi-storied buildings.
摘要:
An elasto-plastic damper is adapted to be used in a structure, such as a building and other facilities, for absorbing vibration energy created by earthquake tremors and other ground vibrations. The damper is a centrally bulged and generally cone-shaped hollow body of revolution so that its section modulus changes substantially proportional to a bending moment created in the damper body due to horizontal stresses, thus permitting a maximum degree of deformability. This elasto-plastic damper is compact in size and demonstrates a high degree of vibrational energy absorbability.

摘要:
A male terminal fitting and a method of manufacturing the same is disclosed as including a plate-shaped contact protrusion (11, 31, 41, 51) formed at one side for mating with a female terminal fitting, and a conductor clamping portion (12, 32, 42, 52) located at the other side for clamping a conductor of an electric wire. The plate-shaped contact protrusion includes a base plate component (14, 34, 44, 54) extending from the conductor clamping portion in a longitudinally elongated shape, and an overlapping fold plate component (15, 35, 36, 45, 46, 55) laterally extending from a side of the base plate component. The plate-shaped contact protrusion further includes a flatness securing plate component (16, 35, 44, 56) laterally extending from the base plate component and overlaps with the overlapping fold plate component to ensure flatness conditions of the base plate component and the overlapping fold plate component. In the method, a plurality of sequentially arrayed male terminal fittings are formed by stamping operation and a forming operation is implemented to form each of the terminal fittings into final shapes, respectively.
摘要:
A laminated hollow rubber damper with increased buckling strength and lengthened period of vibration. The buckling strength of a hollow laminated rubber damper is increased by making at least the inside or the outside wall of the damper of non-uniform section, such as obtained with an arcuately concave wall. By taking advantage of the improved buckling strength of hollow laminated rubber dampers, both the deformability in a horizontal direction and the period of the damper are increased. The hollow laminated rubber damper may be used as a spring element in an active or passive type vibration control device, or as a supporting device suitable for the protection of structures having long natural periods, such as multi-storied buildings.
摘要:
A substantially self-contained vibration control system for building structures. A building has mounted on its roof, or an upper level floor, a hollow concrete-steel first mass carried on high damping rubber supports. Within the hollow of the first mass a second mass is mounted on anti-friction rollers which roll on a low coefficient of friction interior floor of the first mass. The first and second masses are interconnected with a single means to vibrate these masses with a period of vibration which can be synchronized with the vibration period of the building to attenuate building vibration.
