| Abstract: | A new kind of constitutive model the elasto plastic anisotropic damage model of the constructional steel is put forward, which includes the mixed hardening criterion, bauschinger effect, yield plateau, hardening (softening) influence, damage and damage evolution.The model can reflects the real work characters of the constructional steel under the cyclic loads and is suitable for the elasto plastic analyses of the steel structures under the earthquake;and the double nonlinearity FEM of U.L. mode is adopted to analyze the welded columns under the cyclic unaxial force. |
| Keywords: | welded box cross column elasto plastic anisotropic damage constitutive relation cyclic property |
