External GFRP confinement to decrease near-fault earthquake damage of reinforced concrete structures considering soil-structure interaction

In this study, low and medium-rise non-ductile RC frame structures were selected and strengthened by external GFRP confinement. Non-linear time-history analyses, followed by damage analyses, were carried out for the un-strengthened and strengthened frames under different near/far-fault earthquakes, without and with soil-structure interaction (SSI). The obtained results indicated that the external GFRP confinement successfully prevents the...
