Investigation on Seismic Performance of Bidirectional Self-Centering Reinforced Concrete Frame Structures by Shaking Table Tests

Table 2

Acceleration amplitudes of main excitation.

PGA (g)	Level 1	Level 2	Level 3	Level 4	Level 5	Level 6	Level 7
Prototype	0.10	0.20	0.40	0.60	0.80	1.00	1.20
Model	0.13	0.26	0.52	0.78	1.04	1.30	1.56

Levels 1, 2, and 3 represent small, moderate, and large earthquakes, respectively, prescribed in the Chinese seismic design code [23].
