概要
- 論文の詳細を見る
Since partially prestressed concrete has shown superior restoration characteristics, it was proposed to implement it' in bridge piers to reduce residual displacements after earthquake excitations. Small-scaled pier specimens were previously tested using reversed cyclic loading tests. Based on test results, the characteristic behavior of such PRC piers is clarified. Additionally, a restoring force model is proposed. A comparison between results obtained using the proposed model and those from pseudo-dynamic tests is also c〜 nducted. A good agreement is obtained thus verifying the accuracy of the model for implementation in response analyses.
