| Abstract: | The minimum quantity of confining transverse reinforcement in the potential plastic hinge regions of the ductile bridge piers is proposed in the paper.It is based on the nonlinear recurrence analysis.It is studied on that the test data of 25 pieces of flexural columns from three different quasi?static tests.The proposed formula is compared with the worldwide current provisions of seismic design code for highway bridges.It is also compared with the code JTJ 004?89 that is a code of the Ministry of Communications of China.It is found that many useful conclusions are obtained through the study |
