| Abstract: |
| This paper applies a performance-based multidimensional fragility analysis method with the combination of an explicit connectivity Bayesian network to the fragility evaluation of ATC towers.The uncertainty of the earthquakes as excitations is considered.The structural response data is obtained by the nonlinear time history analysis method.The whole tower structure is divided into three levels,and each level is further divided into corresponding sub-levels according to the number of storeys it includes.The damage index and the limit state of the components are determined and the probabilistic seismic demand model which obeys a multi-lognormal distribution is established.Considering the correlation between different limit states,the corresponding multi-dimensional limit state function is established,the corresponding failure domain is analyzed,and the probability of the failure of the component is calculated by Monte Carlo method.The explicit connectivity Bayesian network model of the ATC tower is established and the conditional probability tables of intermediate nodes are established by using Analytic Hierarchy Process.MATLAB is used to perform the inference calculation of the Bayesian network,which achieves the inference from the component fragility to the whole structural fragility. |
