概要
This study confirms applicability of so-called twice-slope method that is one of the limit analyses to evaluate llapse or plastic buckling, to cylindrical struc ture of core internals even when it has cracks. Three lindrical test specimens with radius to thickness ratio equivalent of core shroud were used for monotonic nding test with various condition of cracking to confirm applicability of twice-slope method. The other o specimens with duplicate condition of cracking and dif ferent range of loading were used for cyclic nding test to confirm conservativeness of design margin for limit load even considering cyclic effect of smic load.
