Table 8 Natural vibration period of investigated frames

From: Emerging steel frames with Fe-SMA U-shaped dampers for enhancing seismic resilience

Frame type	T₁/ s	T₂ / s	T₃ / s
HSSF-FED	1.242	0.427	0.241
HSSF-ED	1.204	0.415	0.235
SF-FED	1.171	0.399	0.220
SF-ED	1.136	0.389	0.218

T₁, T₂ and T₃ are the 1^st, 2^nd and 3^rd fundamental period of the frames
