Abstract text:
The study shows the effect of past strong earthquakes that acceleration of near fault earthquakes due to having impact like movement with long periods in the beginning of the record; "directional" have significant differences with far-fault field earthquakes. Adverse effects of such earthquakes increases by approaching cycle time for structures to the period of these earthquakes. In this study, the behavior of steel moment frames equipped with linear and nonlinear viscous fluid dampers with different damping percentage under the effect of far field earthquakes and near and far fault were studied and evaluated. For this purpose, structural models of the 9 floors with moment frame system were selected. With the incorporation of viscous dampers and increasingly dynamic analysis (IDA), the results obtained in the form of diagrams maximum cutting base, relative displacement of floor and residual displacement was introduced.
Key Words:
increasingly dynamic analysis; viscous damper; residual displacement; near fault field
