<p>A method of damping vibration of a structure due to disturbances such as earthquake and wind, and more particularly, to a combination of a damping method, structure and materials, which do not need any special damping device, and which provide high damping effects by applying effective resistance to a slight deformation between upper and lower layers with a simple improvement in construction. In a multi-layered structure such as buildings, comprising columns (1), beams (2) and floors, which bear various loads exerted on a skeleton, as main structural members, and earthquake resisting walls (3) or braces (4), which bear vertical loads and horizontal loads but do not deform horizontally, as auxiliary structural members, a damping structure is such that an upper end or lower end of the auxiliary structural member is fixed to a floor diaphragm (surface constituted by beams and a floor) of the main structural members, and the other end not fixed is joined to another floor diaphragm with a damping element (5) therebetween, which element bears a load and has a damping property. A damping method comprises converting a slight horizontal shearing deformation produced between the layers into a large shearing strain of a thin damping element portion to permit the damping element to absorb vibrational energy when a disturbance vibrates the multi-layered structure. The use of materials such as a highly damping rubber for the damping element enables simultaneous energy absorption and load bearing.</p> |
