| Abstract: | The Beimen Bridge of Sanmenkou Sea-Crossing Bridge is a half-through concrete-filled steel tube arch bridge with a main span 270 m.The static force coefficients of the Bridge were tested and numerically analyzed,the three-component coefficients of its arch ribs were modified by Reynolds numbers and its static wind stability was checked by calculstion.The results indicate that the wind-resistant stability of the Bridge can meet the requirements both at the construction and completion stages. |
