The fuzzy number of the rotational stiffness of the semirigid joint of support is given by the unfamiliarity of the locations of welding the column base into the anchor base plate.
Although software has been written (Eckelman 1970 (4)) for the direct use of semirigid connection factors, semirigid joints can also be treated through the use of short fictitious members (introduced between the end of a rail and the post to which it is connected) that reflect the characteristics of the semirigid joint in question.
provided a simple but excellent fit between joint rotation and moment where [PHI]2 refers to semirigid joint rotation; a and b are regression coefficients; and M refers to bending moment.
Semirigid joint connection factors were then determined by fitting curves of the form
Specimen dimensions, semirigid joint rotations, and semirigid connection factors.
It must be assumed, however, that the cross braces also have semirigid joints with respect to their axial direction.
Tests were conducted to determine the moment capacity and semirigid joint behavior of round mortise and tenon joints with 2-, 3-, and 4-inch-diameter tenons.
One objective of the semirigid joint tests was to determine at what moment level the onset of "yielding" occurs as the joints are loaded to failure.
The deflection characteristics of frames constructed with semirigid joints along with corresponding force distributions may differ substantially from estimates based on rigid joint analyses (Lothers 1960).
