چکیده

In real construction, the loads imposed on gravity load structures (distributed load- concentrated load) with lateral loads including earthquake, wind or landslide due to soil, consideration of all effective factors is required.
In this study, the experimental examination of steel moment resisting frames that is simultaneously affected by concentrated gravity and cyclic loading will be done. The effect of gravity load on cyclic behavior of moment- resisting frame will be investigated. In a moment-resisting frame with certain dimensions, the certain concentrated load will be applied at the middle of beam and according to ATC24 protocol, the lateral cyclic displacement will be created in a frame. By drawing the cyclic diagram for imposed lateral load, the results for various seismic parameters will be evaluated.
The results of experimental data and the obtained results from FEM analysis have been compared for some specimens, which had good conformity with the modeled experimental specimens.
The investigation of experimental and FEM Results indicates the effect of applying gravity load on moment- resisting frame where cyclic displacement is created. The final resistance of steel frame is less than moment- resisting frame without concentrated load such that the total depreciated energy in steel-moment resisting frame without consideration of gravity load is less than 28% of moment-resisting frame with gravity concentrated load.
