A total of twenty beam specimens were made in this study：ten were normal concrete beams and the rest were high-performance concrete beams. The size of specimens was 240 mm ×360 mm ×3500 mm . The parameters included concrete strength, shear span-to-depth ratio, amount of longitudinal steel, amount of shear reinforcement, loading type and strength of transverse reinforcement. The results show that HPC beams have higher cracking and ultimate strengths than normal concrete beams under cyclic load. HPC beams have less strength decay of and lower strain values of shear reinforcement at ultimate. HPC beams have better crack control over normal concrete beams. In addition, HPC beams have better shear ductility than normal concrete beams under cyclic load.
