Abstract:
A supplemental reinforcing structure to be wrapped around a reinforced concrete pier to reinforce the reinforced concrete pier, comprising: a circumferential tensile force earthquake load bearing closed steel plate structure constructed by mechanically connecting adjacent steel elements having adjacent mechanical joint mating edge portions by mechanically joining together said adjacent mechanical joint mating edge portions so as to surround said reinforced concrete pier with a space formed between said reinforced concrete pier and said closed steel plate structure; and a freely formable hardening material filling, and hardened in, said space between said reinforced concrete pier and said closed steel plate structure; said supplemental reinforcing structure further comprising: two steel plate structures stacked one on top of the other with the alternate steel elements displaced relative to the others so that said alternate steel elements extend across the two steel plate structures.
