| Abstract: | Based on bridge deck anti overturn warning system, improving database of the early warning system and expanding scope of warning system application are the goal that can provide early warning monitoring location and threshold for early warning system. By using finite element software, it is conducted a research on reaction condition of simple beam bridge with different sections or span in partial load,comparing of test results and summarizing general rules of the beam plate between the size of the critical load and various influencing factors. |
