| Abstract: | The 2-mass shear type computation model and influence coefficient of aspect ratio are provided in the paper for analyzing the isolated structure system with large aspect ratio. Based on the shear type computation model and influence coefficient of aspect ratio, the acceleration response, displacement response and shear force of super structure are proposed for isolated structure system with large aspect ratio. The analysis results for isolated structure with an aspect ratio 5.01 show that the earthquake response analysis theory has enough precise to use in engineering. |
