Dynamic assessment of curved cable stayed bridge by model updating

The results of the simulations indicate the efficiency and applicability of the presented manual tuning method for updating the finite element model of cable-stayed bridges.

The new aspects regarding effective material and structural parameters and model tuning procedure presented in this paper will be useful for analyzing and model updating of cable-stayed bridges.

As footbridges are unique prototype structures, testing at this late stage does not help very much in the design of the actual structure.

However, combining testing and analysis improves understanding of its vibration behaviour, helps future designs of similar structures and provides key information for the design of remedial measures, if required.

In mathematical logic, an (induced) substructure or (induced) subalgebra is a structure whose domain is a subset of that of a bigger structure, and whose functions and relations are the traces of the functions and relations of the bigger structure.

Some examples of subalgebras are subgroups, submonoids, subrings, subfields, subalgebras of algebras over a field, or induced subgraphs.

A common method to rectify this problem is vibration testing of these structures after construction.In mathematics, an eigenfunction of a linear operator, A, defined on some function space is any non-zero function f in that space that returns from the operator exactly as is, except for a multiplicative scaling factor.More precisely, one has for some scalar, ¿, the corresponding eigenvalue.To provide access without cookies would require the site to create a new session for every page you visit, which slows the system down to an unacceptable level.This site stores nothing other than an automatically generated session ID in the cookie; no other information is captured.
