Framework;  profiled columns;  diagonal braces;  Shaking table test;  Seismic response

Through the simulated seismic shaker test of the 15-layer reinforced concrete special-shaped column diagonal brace frame structure model, the self-vibration characteristics, seismic response time history and spectral characteristics of the diagonal brace frame structure were studied, and the modeling research and theoretical calculation were carried out by using the finite element analysis program of the spatial structure. The calculation model adopts the space beam element and the space plate element, and the material characteristics are taken from the measured value. The self-resonance characteristic values of each order of the structure are obtained through modal calculation, and the dynamic response of the structure is calculated by the direct integration method. From the numerical analysis, it can be seen that the theoretical calculation is consistent with the experimental results.
