| Abstract | ||
| The objective of this paper was to discuss the seismic performance of hybrid FRP-steel reinforced concrete shear wall with replaceable friction dampers at the feet of the wall. The hysteretic characteristics of five wall specimens were studied by pseudo-static loading tests. The results showed that the damage of the specimens was concentrated on the friction dampers, and the energy consumption capacity was increased while making up for the defect of low ductility of FRP reinforced wall specimens. And the repairability of the wall after earthquake was improved. Finally, a calculation method of initial stiffness of shear wall with replaceable dampers was proposed. | ||
