ABSTRACT:
A method for providing earthquake reinforcement for existing buildings by applying pre-compressive or pre-tensile stresses. In a first embodiment, a compression brace is provided on the beam pillar structure of the building in a diagonal direction to the structure so as to apply a pre-compressive stress to the compression brace. In another embodiment, a tension brace is provided on the beam pillar structure of the building so as to apply a pre-tensile stress to the tension brace in order to reinforce the building against an earthquake.
