000011981 520__ $$2eng$$aRotational friction damper (RFD) was introduced in 2000. Primary experimental and numerical studies were done in Denmark. Optimal slip load has the most importance in performance of friction damper. Optimal slip load can be obtained from the minimum of performance indexes. There are two performance indexes, seismic performance index (SPI) and relative performance index (RPI). In this paper three frames equipped with rotational friction damper, are modeled. These frames are studied with different slip loads, acceleration records and PGAs and 540 nonlinear dynamic time history analyses were done to specify the optimal slip loads. The results show that different performance indexes can give similar slip load. Performance of RFD is improved by increasing the heights of the frame. Damage index significantly decreases in optimal slip load. .
