Abstract :

Today, apart from a design perspective structures, The application of advanced technology due to economic considerations, The need to reduce the time and improve the performance of various retrofit projects on the level of risk selection and execution easy to run in cases where there are restrictions Or the need for uninterrupted use of the intended structure is more felt. This study is aimed to evaluate the simultaneous effect of seismic isolator and tuned mass damper on reducing the effect of moment in seismic behavior of steel structures. Therefore 2 model structures of 10 & 15 stories with fixed base, base isolated and a combination of them are evaluated under time history analysis through SAP2000 software using 7 far fault record acceleration and 7 near fault record acceleration scaled to 0.5 g results show that hybrid controlling system is lead to 80% reduction of stories moment in record acceleration of far and near fault earthquakes
