Description
Summary:The setup apparatus described in ASTM A944-10, Standard Test Method for Comparing Bond Strength of Steel Reinforcing Bars to Concrete Using Beam-End Specimens, is designed to apply the load horizontally with respect to the laboratory floor. However, many civil engineering laboratories currently use (or have access to) rigid testing frames designed to apply the load vertically. Thus, a setup apparatus adapted to the current frames in use and alternate to the one described in ASTM A944-10 was developed and is thus presented. Following a brief review of the major characteristics of a typical ASTM A944-10 beam-end specimen, the proposed setup apparatus and the procedure to mount and test the specimen are described. Thereafter, the results of three groups of specimens having three replicas each are presented and are followed by a discussion on how to interpret and analyze the information obtained from the test.
