ABSTRACT
In current seismic design practice, AASHTO, AREMA and IBC are the most popular
specifications for highway bridges, railway bridges and building structures, respectively.
Theoretical speaking, when earthquakes occurred, the structures would be damaged with
no exception regardless of their functionalities. But the seismic design approaches and
requirements in these three specifications demonstrate significant differences in many
aspects.
It is necessary to make a parison of these three specifications in terms
of seismic design in order to carry out reasonable seismic analysis on some multi•
function structures which are including building structure and bridges for vehicles or
trains, or both. A good example of this type of structures is multi•model transportation
center which is normally appearing in metropolitan area. In the seismic analysis of this
type of structure, some additional coordination work among these specifications is critical
in order to achieve correct results.
Theoretical parametric investigations have been made pare these three
specifications in terms of seismic design. Some mendations are provided for
