Abstract:
In this research, the performance abilities associated with tube type lateral load resistant framed systems are studied in order to assess the seismic response parameters of steel tall buildings subjected to both far and near-field earthquake records. For this purpose, four 30 story structural models with framed tube based skeletons were selected and designed. The plans of models are squared shape. The structural response parameters have been computed and obtained by conducting a number of non-linear dynamic time history analyses. The structural models have been designed according to the Iranian seismic code 2800(third edition). Findings from this study reveal that, mean maximum demands and the dispersion in the peak values were extremely higher for near-fault records than far-fault motions. The maximum story drift for the studiedmodels was determined and compared with the “life safety” and “collapse prevention” performance limits, as recommended by FEMA 356.
