Abstract:The purpose of this investigation was to study the flexural strength of concrete beam specimens after repeated loading. The test results showed that some specimens produced an increase in flexural strength after repeated loading. An attempt is made to explain this strength increase. It appears likely that microcracking propagation is responsible for this increase in flexural strength.
