Shaking Table Test of Rectangular CFST Column-Mild Steel Plate Composite Tall Piers
Based on the trial design results of rectangular concrete filled steel tubular(CFST)column-mild steel plate composite tall piers,two scaled models were designed and manufactured.Seismic simulation shaking table tests were conducted to preliminarily verify the seismic performance of the composite tall pier.The results of experiments show that the seismic responses of the composite tall pier models are significantly influenced by the seismic frequency spectrum characteristics and site category,and weak soil will amplify its seismic re-sponses;The composite tall pier models are in an overall elastic state under frequent earthquakes,and the mild steel plates will yield first and dissipate energy under strong earthquakes.
