Stiffness assessment of bridge decks repaired by steel plates using an advanced system identification method

Abstract: This work examines the identification of stiffness reduction in damaged reinforced concrete bridges under moving loads, and carries out the stiffness assessment after repairing using steel plates. In particular, the change of stiffness in each element before and after repairing, based on an advanced system identification (SI) method, is described and discussed by using a modified bivariate Gaussian distribution function. The proposed method in the study is more feasible than the conventional element-based meth… Show more

“…Alternatively, the residual was defined as the relative difference between the measured and computed displacement responses [127]: γ=iYiUfalse(normalqfalse), and the objective function or fitness function was expressed as [127]:minimizefalse(normalFfalse), normalF=truei=1N[γ]2=truei=1N[iYiUfalse(normalqfalse)]2, where 1Y, ,NY denote the measured displacement data; iU: RsboldnormalR(i=1, , N) is the function that satisfies normalU: ΩRsnormalΓRN; normalUfalse(normalqfalse)=[1U2…”

“…Lee et al [127] used μGA and the FEM to analyze measured dynamic displacement responses for identifying the arbitrary stiffness distribution in damaged reinforced concrete bridges subjected to moving loads. The dynamic displacement responses with noise effects were measured from a 3D solid finite element model subjected to a moving load with various velocities instead of real reinforced concrete slab bridges.…”
