he simplified calcalation of aseismic reliability of jointed arch dams is studied. The ability to deform of jointed arch dams is taken as the limit state,the limit deformation of thejoint which responses most intensely is selected as the dominant variable. The effect of structure is described by only one variable,i.e.ground acceleration.The correlation between the effect and poak acceleration is established by calculating the largest deformation induced by the peak acceleration,thus the3-D problem... he simplified calcalation of aseismic reliability of jointed arch dams is studied.

The effect of structure is described by only one variable,i.e.ground acceleration.The correlation between the effect and poak acceleration is established by calculating the largest deformation induced by the peak acceleration,thus the3-D problem is simplified into several 1-D problems. This method is convenient to use in practice. |
