In the revised architecture standard law, equivalent damping factor calculation method has been introduced with the use of seismic response spectrum. Buildings having a natural period of more than 1 second are often studied in previous published researches of this method in comparison to those having a natural period of less than 1 second, such as low-rise steel-frame constructions. The aim of this paper is to study the seismic response characteristic of low-rise steel-frame buildings and the accuracy of equivalent damping factor calculation method. The accuracy is examined by comparing this method value with seismic response analysis result. These buildings are converted into a single-degree-of-freedom system and a bilinear and slip type hysteresis model for this analysis. Both simulated and recorded seismic waves are used for seismic response analyses to also define the influence of seismic types, ranging from long duration to near fault motions types.
