| Abstract: | Based on the static wind force factors of a tower and on the root mean square of the buffeting displacement responses of the tower top, which are measured by wind tunnel tests in laminar and turbulent field respectively, the static and buffeting internal forces of the tower bottom control sections under its design wind speed are obtained by linear superposition method and FEM. |
