Calculation methods of the crack width and deformation for concrete beams with high-strength steel bars

Abstract

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.

Keywords

concrete beam / high-strength steel bar / crack width / deformation
