Height of Beam Section

Figure 13 shows the distributions of bolt forces and M — 9r curves in cases changing the beam height

(d) as d = 203 mm and 359 mm, in which those are for models of A2 and FE10, respectively. From this figure, it is confirmed that the distribution of bolt force and prying force were never effected by beam height and connection moment is increased corresponding to the beam height only.

Mechanical Properties ofAngle

Figure 14 shows the distributions of bolt force and M — 9r curves in cases changing grade of angles as Azizinamini et al.’s test data and A36 steel, in which those are for models of FE1 and FE7, respectively. From this figure, it is confirmed that bolt force is not affected by mechanical properties

of angle but connection moment is upgraded in the elasto-plastic region by using higher strength of angles.
