| Abstract: |
| Based on the requirements of new seismic code for site soil properties and artificial seismic wave selection,this of paper considers the seismic action as a random process,and the stochastic process model acceleration generated by the orthogonal expansion of the modified Hu-Zhou model is modulated through the non-stationary intensity modulation index to generate artificial seismic waves of different soil properties.Taking the nonlinear random seismic response analysis of a 6-storey reinforced concrete structure as an example,the influence of artificial seismic waves on the reliability of structural displacement is studied.The results show that the site soil properties have a great influence on artificial seismic wave generation and the structures dynamic response,and the artificial seismic wave of different sites has obvious statistical characteristics,which meet the requirements of seismic wave selection and provide a new solution of providing seismic waves of different site soil properties for the latest seismic code. |
