| Abstract: | Few studies on the particular issue of unbalanced wind loading on double cantilever bridges have been made in literatures.A method of calculating the equivalent static wind loads on double cantilever bridges is developed herein,to which the solutions are given in analytical forms.A numerical example demonstrates that the analytical formulas given in this paper are not only very simple but also show high precision compared with the theoretical method,and no interpolation in graphs or charts are needed. |
