    Abstract
  • Based on the experiments, the Loland model used in damage mechanics was introduced into concrete uniaxial compression analysis and the descending portion of the model was modified into nonlinear expression.The parameters of the stress-strain relationship for concrete suggested by code for design of concrete structures(GB 50010—2002)were processed by data regression fitting.Combined with the modified Loland model, the concrete salt-freezing damage constitutive model related to freezing-thawing cycle time and water-cement ratio was derived.With the compiling programs by Fortran language, the section nonlinear analysis of RC beam under salt attack, sustaining load and 400 times freezing-thawing cycles was done.The result indicates that under the action of multi-factors, with the increase of the cycle times and the ratio, the initial damage of concrete is growing, the peak stress reduces and its corresponding strain increases, but the ductility is not significant change.With the increase of continuous load, the ultimate bearing capacity of the beam decreases.
