Shaking table test of rural buildings with ring beams and structuralcolumns considering soil-structure interaction effect

Herein, the parametric modeling method was employed in the analysis and design of damping structures. An optimal damper arrangement scheme was developed by presetting objectives and iterative optimization calculations for the energy dissipation structure of a B-level high-rise residential building in Tianshui City. Perform 3D and ETABS software were used to analyze the structural response during frequent and rare earthquakes to assess the seismic performance of the energy dissipation structure. The analysis results show that during small earthquakes, the story displacement, story drift ratio, story moment, and story shear of the energy The setting of ring beams and structural columns is an important measure to improve the overall seismic performance of rural buildings. In this study, a series of shaking table tests considering soil-structure interaction (SSI) was performed on rural buildings with ring beams and structural columns. The 1/4 scaled model of the structure used in the test was manufactured and placed on a foundation soil model. One natural and two artificial seismic waves were selected, and the input seismic amplitudes were 0.1g (7-degree), 0.2g (8-degree), and 0.4g (9-degree). The test results showed that under the action of a 0.4g (9-degree) earthquake, only slight cracks were induced around the corners of doors and windows of the longitudinal wall, and the failure mode was intact, indicating good seismic performance of rural buildings with ring beams and structural columns. With the increase in the seismic action, the acceleration amplification coefficient of the structural model decreased gradually, while the response of the story drift gradually increased. When the seismic intensity is high, the influence of the SSI effect on the acceleration transfer coefficient from the soil layer to the structure should be appropriately considered.
