| Abstract: | The emphasis is laid on the analysis of influence of tension angles and distance of hanging point and fulcrum on mechanical properties of cantilevered cable-stayed VierendeeI truss. When the tension angle is changed,the FEA analysis software of ANSYS is used to calculate the internal force and deformation of the component with the same length and the same distance of hanging point and fulcrum. In addition,when the hanging point is moved,we also use it to calculate the internal force and deformation of the component with the same length and the same tension angle. By means of analysis and comparison,we have found that the influence of tension angles and position of hanging point on mechanical properties of cantilevered cablestayed Vierendeel truss is very remarkable. |
