Abstract
A proper composition of stiffness and ductility parameters is required to obtain a resistant
and economic structure. Accordingly, Chevron Knee Braced Frame (CKBF) seems
appropriate due to its proper seismic performance. The advantage of this system comes to
having the capability of rapid and cheap replacement of chevron knee elements after an
earthquake occurs. In this research, response modification factor and over-strength factor are
determined for CKBF in two statuses of chevron V bracing and chevron inverted V bracing.
The effect of using Easy-Going Steel (EGS) on the knee is also studied in the 3,6,9 and 12
story frames. In addition, the methods used for this purpose are nonlinear static analysis,
linear dynamic analysis and Incremental Dynamic Analysis (IDA). IDAs have been conducted
on 17 records of important universal earthquakes using Opensees software.
