Dynamic Nonlinear Analysis Model for Reinforced Concrete Elements considering Strain Rate Effects under Repeated Loads

변형율속도를 고려한 반복하중을 받는 철근콘크리트 부재의 동적 비선형 해석모델

The current analytical techniques for R/C elements under severe dynamic repeated loads, like earthquake or impact, has two major problems; one is that the effects of strain rate are not considered and the other one is the current model was developed based on flexural behavior only. Thus, this study develops a computer software that can idealize the flexural and shear behavior of R/C elements using several parameters and also can consider the effects of strain rate. The analytical results using the developed analytical technique were compared with several experimental results and were generally satisfied.
