High-performance self-compacting concrete is green compacting concrete, self compacting concrete with excellent performance. Self-compacting concrete appeared to the attention of domestic and foreign scholars, and gradually emerge in various engineering fields.In this paper, based on existing research, self-compacting concrete test data collected by MATLAB fitting analysis, I analyze self-compacting concrete stress - strain curve fitting equation, and the elastic modulus, peak strain and other basic mechanical indicators. Gives the self-compacting concrete beams carrying capacity calculation methods. Finite strip method of analysis of self-compacting concrete beams are given self-compacting concrete beams M-? and ?-x0 curve, obtained the same curve with ordinary concrete beam. Finite element method compared self-compacting concrete beams and the Code law differences, draw, two algorithms are in good agreement with experimental results, calculation of self-compacting concrete beams broaden the thinking and methods. This Chapter 4 of the self-compacting concrete reliability analysis to identify impact of self-compacting concrete beam reliability index factors, and proposed to increase and improve measures for self-compacting concrete beams. I calculate the ratio of load effect, section size, reinforcement ratio, and the compressive strength of the coefficient of variation and coefficient of variation on the formula similar to self-compacting concrete beam reliability index. In engineering design, does not meet the reliability index of self-compacting concrete beams, can improve the material breakdown and partial load factors in the approach to achieving and increasing the partial load factors for improving the reliability of self-compacting concrete beams excellent results Partial factor in the increase of material.
