Abstract

Capability of a rapid jacketing technique for damaged RC column using Ultra High Performance-Strain Hardening Cementitous Composites (UHP-SHCC), was confirmed. UHP- SHCC has tensile strength more than 8MPa and tensile strain capacity more than 1%. Cyclic loading tests for the wall specimens (cross section: 500x1200mm) were conducted. Two kinds of repair materials were adopted; one was ordinary SHCC and the other was UHP-SHCC. Each repair material has similar material ductility (tensile strain hardening) but different tensile strength. The test results showed that the developed technique using UHP-SHCC can be applied to large size of specimens. And not only material ductility but also tensile strength affects recovery of repaired specimens (ultimate strength and energy dissipation).
