The Ultimate Seismic Capacity Research of Concrete Gravity Dam Considering the Initial Crack

Abstract

Based on the typical overflow dam section of Ahai gravity dam, the cracking calculation was conducted and the crack form was determined, referring to the experimental research result. Then the constraint-function contact algorithm in ADINA was used to study the stability of the upper free body subjected to an earthquake. The analysis results primarily show that the ultimate seismic capacity of Ahai gravity dam is an earthquake whose peak acceleration is between 3.4g and 3.8g.
