Seismic response analysis on the prestressed concrete converting truss structure

On the basis of simulating finite element model that according to an actual engineering, the paper uses mode-superposition response spectrum for the calculation of horizontal and vertical seismic actions. In addition, to obtain dynamic time history response of the prestressed concrete conversion truss structure under the seismic action, the paper chooses appropriate ground motion records to simulate the finite element mode via sap2000 as the supplement calculation.
