In these years, high-rise apartment buildings with core wall structural system have been constructed. Since span of coupling beams used in the core wall system is too short, large drift angle will be developed. However, RC short span beams do not have excellent ductility under high shear stress condition during earthquake. To resolve this problem, it was decided to use high-performance fiber reinforced cement composite SHCC (Strain-Hardening Cementitious Composites), which exhibits excellent ductility, for short-span beams.
In this study, shear bending tests under antisymmetrical moment condition of SHCC beam specimens were carried out to investigate their structural performances. The accuracy of the calculated flexural strength and shear strength values was also examined.
