Embodiment Construction
[0057] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0058] In the long-term safe operation monitoring of bridges, the measured structural response signal R is the comprehensive response of the bridge under various actions, which can be expressed as:
[0059] R=F(t,T,D,L,S,O) (1)
[0060] In the formula: F( )——represents the functional relational expression;
[0061] t——represents the time effect;
[0062] T——indicates the temperature effect;
[0063] D——indicates the dead load effect of the structure;
[0064] L——indicates the action of live load;
[0065] S——indicates the effect of test error;
[0066] O——Indicates other functions.
[0067] Therefore, the environment in which bridges operate in daily operation is very complex. It is necessary to remove the influence of environmental factors and extract structural damage information from monitoring signals to obtain correct evaluation re...
