Abstract

The effect of the external pre-stress on the mechanical properties of concrete structure was analyzed, on the basis of the shape memory effect, a new-style pre-stress structure on SMA external pre-stress concrete structure was put forward, the mechanical properties of ordinary reinforced concrete structure and SMA external pre-stress concrete structure have been analyzed comparatively, it is also pointed out in the paper that some problems should be solved before the structure are popularized and applied, and proposed the theoretical bases for engineering application of the external pre-stress structure of SMA for the future, the theoretical analysis show that the actuating effects of the shape memory alloy wires on the deformation of concrete structure can be obtained during phase transformation, the shape memory alloy actuator is successfully utilized as a way to control the crack width of concrete structure, the pre-stress structure can increase the crack resistance and the application of it is feasible.
