| Abstract: | Five self-compacting concrete beams and two corresponding normal concrete beams were designed to study the bearing properties of flexural members of self-compacting concrete,and their cracking loads,utmost loads,average strain in different heights of section,rigidness,and crack were investigated by experiment.And on the basis of methods to calcuate common concrete members,the formulas to calculate the rigidity,crack and ultimate height of compression strain of SCC as well as the method to calculate the bearing capacity were provided. |

| Keywords: | self-compacting concrete (SCC) beam rigidness crack bearing capacity |
