Displacement-based seismic design ( DBSD) is an effective way to realize the philosophy of performance-based design ( PBSD), which has received increasing attention.

The displacement demands of symmetric and asymmetric continuous girder bridges in longitudinal direction are studied, and then a DBSD method is proposed, an example is given.

分别对纵桥向对称和不对称的连续梁桥的固定墩墩项位移需求进行了研究，在此基础上提出了连续梁桥纵桥向基于位移的抗震设计方法，给出了该方法的算例。
