It is often at issue that due to hard site conditions including required temporary works, dredging in the river and headroom constraints, earthquake-resistance retrofitting works are difficult and cost-consuming for existing bridge piers. For solution, we have developed a new method. In addition to pressing into the riverbed and installing steel plates around piers, this method ensures strength of pier ends against bending moment force by extending rebars into the existing footings. This paper reports the experimental results of the new retrofit method on its construction practicability and quality, hysteretic characteristics, cyclic loading tests, reinforcement effectiveness, etc.
