A Solution for Internal Force and Nodal Displacements of Statically Indeterminate Plane-converging Truss Structure

By using the bar geometry of deformation and displacement for the statically indeterminate plane-converging truss structure,the horizontal and vertical displacements of the node uand vare converted into an equation containing only two unknowns.It provides a convenient way for the establishment of a statically indeterminate.Teaching practice shows that the method has a clear concept,easy to grasp and easy to appl to procedures.In addition,the method is also applicable to the statically determinate plane-converging structures and space concurrent truss structures.
