عنوان فارسی ارزیابی عملکرد لرزه ‌ای سدهای بتنی وزنی-قوسی با استفاده از تحلیل دینامیکی افزایشی
چکیده فارسی مقاله درگذشته تحلیل لرزه‏ای سدهای بتنی اغلب به‏صورت ایده آل با استفاده از مونولیت‏های دوبعدی در سازوکار تحلیل و طراحی در نظر گرفته‏شده و اثرات زلزله معمولاً با تعریف یک ضریب زلزله اعمال می‏شده است. اما در سال‏های اخیر تأکید بیشتر بر تحلیل‏های تاریخچه زمانی غیرخطی و نیز آنالیز شکست سدهای بتنی در فضای سه‏بعدی شده است. همچنین با پیشرفت دانش درزمینه‌ی مهندسی زلزله و توسعه روش‏های دقیق‏تر برای برآورد شدت زلزله‏های محتمل ازجمله روش تحلیل دینامیکی افزایشی، فرآیند تحلیل و ارزیابی لرزه‏ای سازه‏ها کامل‏تر گردیده و تأثیر پارامترهای بیشتری را می‏توان در ارزیابی ریسک هر سازه لحاظ کرد. در تحقیق پیش رو، پاسخ لرزه‏ای سدهای بتنی وزنی-قوسی تحت اثر تحریکات زلزله در یک تحلیل المان محدود سه‏بعدی بررسی می‏شود. اثرات ناشی از در نظرگیری اندرکنش سد-مخزن-پی، رفتار غیرخطی بتن و همچنین الگوهای متفاوت شعاع قوس سد مطالعه شده و درنهایت سهم پاسخ هریک از عوامل پایداری در برابر تحریکات لرزه‏ای مورد ارزیابی قرار می‏گیرد.

عنوان انگلیسی Seismic performance evaluation of concrete arch-gravity dams using incremental dynamic analysis
چکیده انگلیسی مقاله The Seismic analysis of concrete dams had been considered in an ideal form by means of two dimensional Monoliths in analyse and design procedures and structures had been subjected to ground motions with defining seismic coefficient. Lately, the research focus, however, has been more on linear time history analytics and fracture analysis of concrete dams in 3D space. With the advancement of knowledge in the field of earthquake engineering and the development of more precise methods for estimating the intensity of possible earthquakes, The methods of analyzing and evaluating the seismicity of the structures have been improved and the effects of more parameters can be considered in assessing the risk of each structure. In the present study, the seismic response of a concrete arch-gravity dam under the influence of earthquake stimulation is investigated in a three dimensional finite element analysis. The effects of dam-reservoir-foundation interactions are considered and the nonlinear behavior of the concrete and also the different patterns of the arc radius of the dam are studied. Finally, the contribution of response of each of the sustainability factors to seismic stimulation is evaluated.
