Abstract

Abstract

It is studied a steel tube's three-dimensional stress and core's concrete constraint mechanism by plastic mechanical theory.It is also considered that steel tube's three dimensional stress meets R.Von Mises yield condition at plastic stage.Three-dimensional compression of the cure concrete can increase greatly the ultimate bearing capacity.With different core concrete failure criterion,and different results can be got.
- three-dimension stress,
- core concrete,
- constraint mechanism,
- ultimate bearing capacity,
- failure criterion
