摘要:

The thesis mainly talks about a single-layer latticed cylindrical shell with 1.8 m in length and 1.8 m in span, and a shaking table test of soil-independent foundation-latticed cylindrical shell was realized based on a model box with 7.7 m in length, 3.2 m in width and 1.2 m in depth. Then, the seismic responses of soil-independent foundation-latticed cylindrical shell subjected to different earthquake waves were studied. At the same time, a finite element model of shaking table test was established, and the numerical simulation results were compared with the test results. The results show that the test results and numerical results are in good agreement, and the peak acceleration of foundation increase compared to the peak acceleration of free field. The sliding and separation phenomenon between soil and foundation is a principal factor to affect the error between test results and numerical results. The nonlinear relationship between soil and foundation become more apparent along with the increase in vibration frequency. The spectrum characteristic of different earthquake waves is also an important factor to affect the seismic response of soil-independent foundation-latticed cylindrical shell. The resonance phenomenon should be paid more attention to between structure system and dominant frequency of earthquake wave to avoid the distortion of test results when a shaking table test is designed. © 2017, Central South University Press.
