The Study of Self-Compacting Concrete Stress -Strain Curve Equation and Reliability Analysis of Beam

Free vibrators is a high performance self-compacting concrete green concrete , self-compacting concrete with excellent performance . Self-compacting concrete appeared to get the attention of scholars at home and abroad , and gradually emerge in various areas of engineering . In this paper, on the basis of the existing domestic and international research , collect self-compacting concrete test data analysis by MATLAB fitting self-compacting concrete stress - strain curve fitting uniform equation , and the elastic modulus , peak strain mechanical index . Self-compacting concrete beams bearing capacity calculation methods are given . Finite strip method of nonlinear analysis of self-compacting concrete beams , self - compacting concrete beams M - ? ?-X0 curve , similar to ordinary concrete beams . Compare the finite element method to calculate self-compacting concrete beams with the \Chapter 4 of this paper to analyze the self-compacting concrete reliability , load effects than the cross-sectional dimensions, reinforcement ratio were calculated , and the compressive strength of the approximate coefficient of variation of the coefficient of variation and formulas reliable indicator of self-compacting concrete beams . Identify the impact of self-compacting concrete beams normal section bearing capacity of a reliable indicator of the factors , and to enhance and improve the measures a reliable indicator of self-compacting concrete beams . In engineering design , does not meet a reliable indicator of the self-compacting concrete beams , can improve the way of material breakdown and partial load factors to achieve , and increased partial load factors for improving the effect is excellent since the compacting concrete beams reliability , in increased material partial factor .
