Introduction Finite Element (FE) model updating entails tuning the model so that it can better reflect the measured data from the physical structure being modeled [1]. One fundamental characteristic of an FE model is that it can never be a true reflection of the physical structure but will forever be an approximation. In other words, FE updating fundamentally implies that we are identifying a b...

The following study deals with the updating the finite element model of structures using the operational modal analysis. The updating process uses an evolutionary optimization algorithm, namely bees algorithm which applies instinctive behavior of honeybees for finding food sources. To determine the uncertain updated parameters such as geometry and material properties of the structure, local and...

A novel energy-dissipation system for frame-core tube structure equipped with damped outriggers is studied experimentally. A steel frame-core tube structure model is designed and manufactured, in which viscous dampers are inserted vertically between the outrigger and fame columns to make full use of motion discrepancy of these two components. Shaking table tests of the building with damped or f...

In the initial construction of unit-level virtual models in discrete production system, understanding physical entities and actual operating environment is lacking, need to be iteratively updated resemble more closely. To solve above problems, an updating method for knowledge model driven by data studied. Firstly, behavior can divided into basic functional such as forward kinematics, trajectory...
