Improving Resistance of Gravity Dam to Seismic Wave by Using Stepped Base

This study analyzes the possible modes of the seismic wave for concrete gravity dams and the damage occurring in the body where two gravity dam sections are taken as a case study. Model (1) is a typical section of a gravity dam, while model (2) is a gravity dam section provided with specified steps...
