The tendency to build cable arch stayed bridges is increasing due to their aesthetic appearance and efficient performance. Due to overloading or time passing, they may face deformation thus they are required to be reshaped. For the same explanations the cables could undergo high tension and some others face slack, in order to keep the bridge safe in terms of stress failure, the redistribution of internal force of cables is essential. Pragmatically, the displacement restoring and the force redistribution are simultaneously necessary, since both issues arise together. This paper deals with simultaneous control of nodal displacement and internal force of cable theoretically by MATLAB Program and experimentally of a linear and a geometrically nonlinear model. The paper also shows that how the technique of adjustment response to control linear and geometrically nonlinear structures. It was determined that the technique was pragmatic and effectual for linear structures. While it was not very accurate for geometrically nonlinear structures, since more than one iteration was required to get the target. [ABSTRACT FROM AUTHOR] |
