| Abstract: | The cable-strut portal frame is modeled by beam, truss and cable element. To make clear the influence of such factors as strut number, strut section area, prestress in cable, cable section area and the deflection to span ratio of cable on the load-carrying behavior of this kind of structure, parameter analysis is carried out with a mixed finite element program, from which some useful conclusions are drawn. |
