Short-span beams that connect core walls in super high-rise apartment buildings are subjected to high stress and deformation during a great earthquake. An attempt is now being made to use strain-hardening cementitious composites (SHCC) with great shear strength and high ductility in short-span beams. Loading tests for SHCC beams have revealed the following points. 1) SHCC beams suffer flexural failure at a shear redundancy of 1.25 or higher. 2) Critical rotation angle of member R exceeds 1/20 rad and SHCC beams provide sufficient ductility at a shear redundancy of 1.35 or higher.
