Check of a Suggestion on Earthquake Action in Guide Specifications for Seismic Design of Highway Bridges of China

Abstract

The improvements on earthquake action suggested for new version guidelines for seismic design of highway bridges of China is checked by NGA-west2 data in this paper. The result shows a clear feasibility with some degree of safe redundancy on whole, especially at long period range. The horizontal design spectra are similar with those in the existing version, and the vertical one are improved a lot.
