  • Patent number: 7040176
    Abstract: A member of an earthquake-proof reinforcement structure is selected with reference to the allowable stress intensity ratio of the member, a ductility factor ratio allowable as a deformation magnification by earthquake-proof reinforcement of the selected member is set, an increase in load in a plasticity range, which acts on the selected member, is calculated on the basis of the set ductility factor ratio, and a corresponding allowable stress intensity ratio is obtained. When the obtained allowable stress intensity ratio is defined as a maximum value of 1.0, the corresponding increase in load in the plasticity range is specified as an ultimate load at which the selected member collapses.

  • Patent number: 6438904
    Abstract: The present invention provides a root wrapping type aseismic reinforcement construction and method for a base of a column member. A buffering portion is provided between the base of the column member and a root wrapping member to decrease bending moment generated on the base by an external force. Therefore, the bending moment is less prone to be transmitted to a foundation member, so that the bending moment born by the foundation can be reduced.
