Abstract:Pullout tests with headed studs placed near a free edge have been carried out. In most of the tests, blow-out failure occurred. On the basis of this and other available test results, an empirical equation to calculate the failure load was derived. The equation takes into account the influence of the edge distance, the concrete strength, and the load-bearing area. The equation to calculate the failure load shows good agreement with the test results. The equation to calculate the critical edge distance at which the failure mode changes to steel rupture or to concrete cone failure is given. The values for critical edge distance are different from the values in ACI 349, Appendix B, because ACI 349 overestimates the concrete capacity for large edge distances.
