Abstract

For the seismic design of steel framed structures the randomness in yield strength due to different origins is an important aspect in view of the structural regularity, because the energy dissipation capacity should be shared by possible plastic hinges distributed as uniformly as possible over the structure. In this study the influence of the randomness in yield strengths on the energy dissipation capacity of steel framed structures represented as behavior factors is investigated with 7 steel framed models. Also 4 artificial accelerograms simulated with a given spectrum are applied to check the randomness in seismic inputs. To execute numerous time-step calculations for the investigation a time-step analysis method is developed and applied to determine the action effects after the reliability estimation.
