Load-bearing control of slender bridges

An active control of the load-bearing capacity of slender bridges is treated in the present paper. Interactive conditions in ultimate response are considered. A numerical treatment of the occurring/appearing non-linear problems is made using the updated Lagrangian formulation of motion. Each step of the iteration approaches the solution of linear problem and the feasibility of the parallel processing FETMtechnique with adaptive mesh refinement and substructuring for the analysis of ultimate behaviour of bridges is established. Application to an actual bridge is submitted in order to demonstrate the efficiency of the procedures suggested
