Investigating the Effect of Using Seismic Separators on Seismic Improvement of Steel frames
Author(s):
Abstract:
The idea that a building can be uncoupled from the damaging effects of the ground movement produced by a strong earthquake has appealed to inventors and engineers for more than a century. Seismic isolation is effective in reducing seismic demand for buildings and decreasing seismic damage costs. Today the concept has matured into a practical reality and is taking its place as a viable alternate to conventional (fixed base) seismic resistant construction. This study, three bracing frame and three spacial moment frame were modeled and analyzed and the capacity curve wase plotted.The finaly, response modification Factors for steel frames equipped with base isolation were compiled as a table.Finally, based on the results of the analysis, it was observed that the structures equipped with the surface separator have a more obtuse curve than the non-separating state.
