Abstract:
Strut-and-tie modeling is a valuable tool for designing irregular concrete members. The ACI 318-02 Building Code contains provisions pertaining to design using strut-and-tie models. This paper presents the experimental results of tests conducted on small-scale, simply-supported dapped beams with openings. The design of each test specimen was developed by independent student teams using the ACI provisions for strut-and-tie models. Each of the four specimens resisted loads greater than the factored design load and exhibited little distress at service load levels. The successful test series illustrates the applicability and conservative nature of strut-and-tie modeling for design.
