The anchorage capacity of the cone shaped splitting failure is focused in this paper. The cone shaped splitting capacity is examined by the pull-out testing with the series of twenty-nine specimens. Transference of stress from the anchored beam rebars to the concrete at the potion that is simulating the beam-column joint is observed. The results of the tests suggest the followings : l) The cone shaped splitting capacity is corresponding to the lateral tensile capacity of concrete and hoop reinforcements in the beam-column joint. 2) Anchorage strength in case of the side burst failure is estimable as safe with the existing empirical formula. 3) The maximum bearing stress at the anchor-heads is three times as large as the compressive strength of concrete. This paper also proposes a simple model to estimate the bond stress of the anchored reinforcements in the member with flexural stress
