| Abstract: | Through establishing the middle span section space pattern of large span continuous rigid frame,the paper calculates and analyzes by the large universal finite elements procedure ANSYS,compares and studies the influence of box bottom cross rib on direction across bridge stress,so as to reach the controllability of down warping in the main span of continuous rigid frame. |

| Keywords: | continuous rigid frame box beam bottom cross rib space effect |
