Seismic Performance of Strain-Hardening Cement Composite (SHCC) Squat Shear Walls with vertical slits

Abstract:

This study investigates experimentally the applicability of selectively weakening retrofit for existing and non-ductile squat shear walls. To evaluate the effect of vertical seams on the wall panel on the hysteretic behavior and failure mode of Strain-Hardening Cement Composite (SHCC) squat shear walls, two 1/3 scale shear walls with vertical seams as a variable were made and tested under reversed cyclic loadings. All specimens had same rectangular cross-section 1,100mm¡¿50mm, with panel height 600mm. The vertical seam is 40mm wide and 260mm high and 460 high. SHCC for wall specimens was supplied by a local ready mix company with specified strength of 50MPa. The test results of this study; length of the slit is increased in squat shear wall, which the specimen became load-carrying capacity and stiffness. But have vertical silt, the squat shear wall shows aspects of ductility destruction.
