APPENDIX E E. COMPARISSON OF THE MODELS WITH CIRCULAR AND SQUARE BOLT PATTERN 215
The simulated tri-linear hysteresis characteristics of the models with circular and square bolt pattern are presented in pair in this section. Close examination of the results presented reveal that in majority of the cases, using the circular bolt pattern may improve the moment capacity, stiffness, ductility, and eventually the overall energy dissipation of the connection. 216
