Large-Beam Tests on Mechanical Behavior of Dam Concrete under Dynamic Loading
Publication: Journal of Materials in Civil Engineering
Volume 27, Issue 10
Abstract
The objective of this study was to determine the tensile behavior for dam concrete under simulated earthquake loading conditions (loading frequency 5 Hz). Four-point loading tests were conducted on large beam specimens (). This paper describes the behavior of dam concrete subjected to dynamic elevated-amplitude cyclic loading with different initial static load levels. Stress-strain measurements were made on the concrete specimens. The test results show that dynamic increase factor of dam concrete increases with increasing initial static stress levels. The results of this study should be useful in determining the earthquake resistance of dam structures.
