<P>PROBLEM TO BE SOLVED: To provide a tension type base-isolation bearing device to be arranged between an upper structure and a lower structure of a building or a civil engineering structure such as a bridge such that a structure bearing device being made thin, compact, and low-cost, and attenuating energy of an earthquake by paying attention to ductility by tensile force of rubber against large inertial force of the upper structure during an earthquake. <P>SOLUTION: A structure bearing device 1 includes a first member 11 arranged at one of the upper structure and lower structure; a second member 7 arranged at the other; and an elastic material which has a radial part 13c arranged horizontally and radially between the second member 7 and first member 11, and is made of a tensile rubber material. The bearing device is configured to absorb energy with tensile force added to the elastic material against horizontal displacement in all directions added to the structures. <P>COPYRIGHT: (C)2013,JPO&INPIT |
