Sažetak
Blind bolted connections enable simple joining of various beams to tubular columns. In the parametric analysis several different blind bolts systems were compared through the example of I-beam-to-hollow section column joint with extended endplate. 1155 combinations of parameters defining behaviour of considered joint type were analysed. The size of a bolthole or more precisely blind bolt geometry has major effect on joint resistance. The most common failure mode is bending of the column flange. In the cases where the thickness of the endplate is lower than or equal to the thickness of the column wall, endplate most frequently fails by bending. Obviously the use of an elliptical yield line mechanism and appreciation of the membrane action effect increase the joint resistance. It is suggested to investigate further the membrane action effect with the use of elliptical yield line mechanism especially in the region where the failure mode changes.
