Pseudodynamic Testing of Buildings Retrofitted with External Steel Reinforced Concrete Frames to Increase Lateral Strength for Earthquake Damage Prevention

<div>Cracks appeared in the PD-F specimen during pseudodynamic testing at 300 gal, after (a) 1.52 s with lateral displacement of 10 mm and force of –204 kN, (b) 2.18 s with lateral displacement of 24.9 mm and force of –268 kN, (c) 5.4 s with lateral displacement of 28.9 mm and force of 80 kN, and (d) during the final stage (7 s).</div>
