EVALUATION OF SEISMIC RESISTANCE FOR AN OLD WATER STRUCTURE IN EGYPT USING DYNAMIC TESTING
Rana Nasser Ellaithy Hamed;
Abstract
Summary :
Scope of the research is to propose a methodology for the assessment of the dynamic resistance of a hydraulic structure. This objective was reached by studying the effect of dynamic loads on the hydraulic structures; case study El-Ayat regulator. A hydraulic structure may expose to many 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 to earthquake but also the dynamic characteristics of the structure. In this research; ANSYS Software, 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 were used to verify the numerical model by comparing the results of the tests with the model’s results and updating the model. Finally, seismic analysis was held to the regulator using different 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 other important results for the decision makers.
