The analyses aim at evaluating the seismic capacity of the building. Results are also presented for 50% increased earthquake intensity. By considering only one-component motion along the axis of no symmetry, three non-linear static procedures are examined: the so called Modal Pushover Analysis, the N2 method as it was extended for asymmetric buildings and the FEMA recommended procedure for two variations of horizontal load pattern (modal and uniform). It was observed that all three methods, especially the Modal Pushover method, may lead to results in good agreement with those obtained by dynamic analyses for design level earthquakes. However, for increased earthquake intensities, when the behavior of the building is strongly affected by the yielding of structural components, the results differed significantly. In this case nonlinear dynamic analysis appears to be the only appropriate method for the evaluation of the seismic capacity of the building.
