- Abstract
In this paper, the calculation of the space deformation of thin-walled element by "dynamic coordinate method" is explained in detail through an example. The thin-walled element with different shear-centers on one section is analyzed and calculated by this method as well, then, the element flexibility matrix is presented. Some difficulties in calculation of thin-walled structures with "plane bending theory" and "constrict twist theory" are overcome, showing the advantages of this method.
