Relying on a single span suspension bridge, using the commercial finite software ANSYS, analyzes and studies the effect of temperature on displacement of suspension bridge beam end, and the temperature field of practical engineering is decomposed into the overall temperature gradient, temperature gradient of cable girder, tower and other temperature gradient temperature difference temperature mode. The finite element numerical calculation analysis is showed that: the overall temperature is taken the leading role of the displacement of the suspension bridge beam end, the temperature difference between beam and other components is with less obvious influence on the beam end displacement. while it is respectively lay the temperature sensor and displacement sensor in the beam and beam, it is feasible that the healthy monitoring in the long-term for beam temperature and displacement and establishing the correlation between temperature and beam end.
