摘要
Three groups of concrete beams reinforced with high-strength steel bars were tested,and the crack width and deformation of the specimens were observed and studied.To facilitate the predictions,two simplified formulations according to a theory developed by the first author were proposed.The advantages of the formulations were verified by the test data and compared with several formulas in different codes.
