利用作平面运动刚体两点线位移在其连线投影相等及相对、牵连、绝对线位移间的矢量关系可迅速求解有斜柱刚架各边相对线位移。
The conventional approach to the solution of the relative linear displacements between elementends in frames with inclined columns is to find the expressions of the general relationships,which it is troublesome to deduce and inconvenient to memorize and to use.In this paper,a new approach is presented in which the solution can be promptly obtained by equating the projections of the displacements of two points in a rigidbody in plane motion along the line connecting the two points and by using the vectorial relationship among relative,carrier and absolute linear displacements.
