Extending of the merchant-rankine formula for the assessment of the ultimate load of frames with semi-rigid joints

Review on the modelling of joint behaviour in steel frames

“…Other international codes of practice which also consider joint behaviour are those of the USA in AISC-ASD [29], LRFD [30], AISC-ASD/LRFD [31] and China in GB [32]. There is currently a great range of studies of steel frames with semi-rigid connections: Jaspart [33], Jaspart and Maquoi [34], Weynand et al [35], Chen [36], Braham and Jaspart [37], Ashraf et al [38], Cabrero and Bayo [39], Bayo et al [40], da S. Vellasco et al [41], Ashraf et al [42], Yang and Lee [43], Faella et al [44], da Silva et al [45], Daniũnas and Urbonas [46], Sekulovic and Nefovska-Danilovic [47], Bel Hadj Ali et al [48], Ihaddoudène et al [49], Mehrabian et al [50], Darío [51], etc. These studies were concerned with two principal themes [52]: (1) the evaluation of the mechanical properties of the joints in terms of rotational stiffness, moment resistance and rotation capacity, and (2) the analysis and design procedures for frames including rotational joint behaviour.…”
