Abstract Scope of the research is to propose a methodology for the assessment of the dynamic resistanceof a hydraulic structure. This objective was reached by studying the effect of dynamic loads on the hydraulic structures; case study Elayat regulator. A hydraulic structure may expose tomany types of dynamic loads such as earthquakes and vehicles flow. Effect of seismic load on hydraulic structures not only depends on to the value of the peak ground motion due toearthquake but also the dynamic characteristics of the structure. In this research; ANSYSSoftware, workbench module was used to create a finite element model for the structure. Field tests were held to determine the dynamic characteristics of the structure and their results wereused to verify the numerical model by comparing the results of the tests with the model{u2019}sresults and updating the model. Finally, seismic analysis was held to the regulator usingdifferent Peak Ground Acceleration (PGA) levels to reach the failure condition to evaluate the seismic resistance of the regulator. It was found that an earthquake with 7.3 magnitude on the moment magnitude (Mw) scale caused a stability failure for the regulator. And many otherimportant results for the decision makers |
