QUANTITATIVE EVALUATION OF EARTHQUAKE-DAMAGED RC PIERS
|
|---|
| 抄録（英）： |
To evaluate the relationship between the damage level and the ultimate bearing capacity of piers, a quantitative investigation was conducted on the RC single piers along the Hanshin Expressway Kobe Route, which were severely affected by the 1995 Hyogo-ken Nambu Earthquake. According to the results of the investigation, 72 piers ranked As and A (severest damage and severe damage, respectively) and had termination of reinforcement at the column mid-height were all damaged at the termination point. Their average shear strength index was smaller than the index of piers ranked B1 or below. There were also 11 piers ranked As and A that were damaged at the column mid-height, even though their reinforcement was not terminated at that point. These piers were found to have a shear strength vs. flexural strength ratio of below 1 and an extremely small shear strength index.
