| Abstract: | Based on the analytical and numerical methods, this paper analyzes, summarizes and discusses several issues in detail on seismic-resistance computation of flumes according to the related contents of the revised specifications (Specifications for seismic design of hydraulic structures). These issues include the equivalent model of sloshing fluid, vertical seismic response and the TLD effect of fluid etc. The defects of computational approach introduced by the revised specifications are pointed out. The modified suggestions and computational methods are proposed for the revision of the code and the seismic-resistance research of the flumes. |
