Seismic performance of R/C frame with precast secondary walls using high performance fiber reinforced cementitious composite

This paper proposes a damage mitigation technique for post-earthquake functionality of the reinforced concrete frame using high-performance fiber-reinforced cementitious composites (HPFRCC) secondary walls. A static loading test of a 1-story 1-span full-scale specimen was conducted to verify functional continuity after big earthquakes. As a result, it showed that post-earthquake functionality can be secured as long as a story drift angle is 1/200 rad or less. In addition, as a result of seismic response analyses of a 5-story RC model building using the HPFRCC secondary walls, it revealed that the maximum response value was approximately 1/200 rad. © 2021 Architectural Institute of Japan.
