A material model with softening effect considered

摘要：

　　Precise analysis on large-span spatial structures depends on accurate numerical material constitutive model,According to the axial tension stress-strain curve,the paper proposes a new numerical multiline material model,with material effects of intenerating effect,material hardening effect and damage effects considered,and corresponding calculation method applicable to beam element.Simulation of axial tension test and bi-level loading test on cantilever column proves that the material model and algorithm are effective and correct.
