Title: Behavior and Efficiency of Bottle-Shaped Struts

Abstract:Experimental research was conducted to determine the strength of compressed struts for use in strut-and-tie modeling. The results were used to evaluate both the safety and accuracy of ACI 318-05, Appendix A, and AASHTO LRFD provisions for the strength of struts. Twenty-six specimens were tested to failure. The specimens consisted of concrete panels loaded in the plane of the panel. The various reinforcement layouts within the panels were used to examine the reinforcement requirements given in ACI 318-05, Appendix A. The results indicate that the use of the ACI expression regarding the amount of reinforcement required in a strut produce conservative but erratic results when compared with the test data. Conversely, AASHTO LRFD expressions are more consistent but somewhat less conservative.
