| Abstract: | Based on the moment theory of thin shell cylinder,internal forces and deformations of column shaft under the effect of gusset are formulated.And in this paper internal forces of tower columns with four different sections are calculated on the action of axial forces and additional bending moments.Meanwhile,the influence of local stress caused by the additional transverse moment on the column shaft is carefully discussed.The relationship between the sizes of gussets and the maximum combined stresses in column shafts has also been investigated in this paper. |
