Özet:

During the earthquake, high and heavy loads in the structural systems may occur not sufficiently small locations in the carrier elements. This change of place brings the second step effect with it. On the other hand, nonlinear static analysis in determining earthquake resistance of structures is often used by designers. With this study, the effects of the second stainless steel in flat steel frameworks have been studied by nonlinear static analysis. Frame-type structures have been analyzed taking into account and not taking into account the effects of the second staircase. Two separate performance curves are created for each frame. With the height of the floor height increased the value of change in the frame. For the condition that the ratio between the floor floor height and the normal floor height is greater than two and two, it is recommended to take into account the effects of the second floor in the structural design.
