| Abstract: | By analyzing measured value of the camber and theoretical value of camber of RPC low-altitude T-beam at the stretching stage,a comparison certifies that the pre-stress's stress is controlled accurately,and the loss of pre-stress is cal- culated correctly,which means the theoretical calculation method of camber is feasible. |

| Keywords: | low-altitude T-beam loss of pre-stress camber RPC |
