Seismic force reduction factors used for equivalent static design of chevron-braced steel frames Part Ⅰ. Equivalent single-degree-of-freedom model

摘要

The proposed ESDOF model can fully be determined using Equations (2), (5-9), and Fig.2. The validity of the ESDOF model will be demonstrated by comparing the seismic performance of the ESDOF model and the corresponding multi-story braced frame. The result is shown in the second part.
