Abstract EN
Displacement-based seismic design methods support the performance-based seismic design philosophy known to be the most advanced seismic design theory.
This paper explores one common type of irregular-continuous bridges and studies the prediction of their elastoplastic displacement demand, based on a new nonlinear static procedure.
This benefits to achieve the operation of displacement-based seismic design.
Three irregular-continuous bridges are analyzed to advance the equivalent SDOF system, build the capacity spectrum and the inelastic spectrum, and generate the new nonlinear static analysis.
The proposed approach is used to simplify the prediction of elastoplastic displacement demand and is validated by parametric analysis.
The new nonlinear static procedure is also used to achieve the displacement-based seismic design procedure.
It is tested by an example to obtain results which show that after several combinations of the capacity spectrum (obtained by a pushover analysis) and the inelastic demand spectrum, the simplified displacement-based seismic design of the common irregular-continuous bridges can be achieved.
By this design, the seismic damage on structures is effectively controlled.
