| Abstract: | According to the principle of axial compressive strength of concrete increases with the increase of other biaxial stresses,and on the basis of the shape memory effect,a new type pre-stress structure-the ring pre-stress structure of SMA was put forward,it is also pointed out in the paper that some problems should be solved before the ring pre-stress structure of shape memory alloy are popularized and applied,as well as the research direction concerned. |
