The numerical results indicate that the properties of time-dependant curves are basically the same and steady under the excitation ofthree simulated seismic waves. The radiant beam string structure has well seismic behaviors.
Keywords: radiant beam string structure; time history analysis; time-dependant curve; dynamic performance
