| Abstract: | Using a space miss finite element program, the author conducts mechanics analysis of a 125 m span special - Shaped steel box beam footbridge and of its loading features. Then the author defines its control force section and imitates the loading method of dense population adopting huge water bags to make a static load test. The experiment result is in accordance with the theoretical calculations, which indicates that the mechanical performance of this bridge is good. |
