Constitutive parameters of the steel material were determined experimentally to guarantee proper assessment of non-linear behavior of the structure. The dynamic responses of the hall to uniform and non-uniform kinematic excitation were compared. It occurred that although, for both cases of excitation, the hall lost dynamic stability and the bolted connections were partially disintegrated, some substantial differences were recognized. Despite the fact that the model of uniform excitation resulted in larger global deformations, due to greater values of maximal average accelerations, smaller values of yield measures, and connection degradations were reported in this case. This phenomenon is caused by quasi-static effects occurring in case of non-uniform excitation. Due to excitation nonuniformity, rafter-to-rafter and column-to-rafter connections were affected by additional torsion and bending, resulting from different motions of column footings, leading to larger deterioration of end plates, and failure of bolts. Hence, disregarding non-uniformity of excitation led to non-conservative results, and caused an underestimation of dynamic response of the hall.
