Response of RPC-Filled Circular Steel Tube Columns under Monotonic and Cyclic Axial Loading

Table 3

The lateral deformation coefficient of concrete with different strengths.

Concrete	Compressive strength (MPa)	Load level
		0.2fc	0.6fc	0.8fc	fc
NSC	30–60	0.17–0.22	0.19–0.26	0.22–0.47	0.22–0.57
HSC	60–100	0.18–0.24	0.19–0.25	0.22–0.25	0.26–0.36
PRC	100–170	0.17–0.24	0.19–0.25	0.22–0.25	0.25–0.31

Note. f_c is the compressive strength of concrete.
