SIMULTANEOUS FORCE AND DEFORMATION CONTROL OF CABLE ARCH STAYED BRIDGES

Abstract

The tendency to build cable arch stayed bridges is increasing due to their aesthetic appearanceand efficient performance. Due to overloading or time passing, they may face deformation thusthey are required to be reshaped. For the same explanations the cables could undergo hightension 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 displacementrestoring and the force redistribution are simultaneously necessary, since both issues arisetogether. This paper deals with simultaneous control of nodal displacement and internal forceof cable theoretically by MATLAB Program and experimentally of a linear and a geometricallynonlinear model. The paper also shows that how the technique of adjustment response to controllinear and geometrically nonlinear structures. It was determined that the technique waspragmatic and effectual for linear structures. While it was not very accurate for geometricallynonlinear structures, since more than one iteration was required to get the target.HTTP://DX.DOI.ORG/10.30572/2018/KJE/10040
