Abstract:

The urban bridges based on performance design are the main development direction of the future engineering design in the world. The aseismic idea and method of urban bridge based on performance are the development trend of aseismic design and technical development of bridge in the world. The connotation based on performance design is expounded. The new trend of urban bridge aseismic design development based on performance at home and abroad is introduced. The deficiency and striving direction of this field in China are analyzed and thought. The relevant proposals are put forward.
