Response analysis of giant-subtype control structure system under vertical seismic action

Giant-subtype control structure system;  vertical earthquakes;  complex mode theory;  Non-stationary shaking

The reaction mechanism of the mega-subtype control structure system MSCSS (Mega-sub eontrolled structural system) under the action of vertical earthquake was analyzed, and MSCSS with additional columns was proposed. MSCSS with additional columns can not only solve the problem of large span of giant beams in structure, but also have good control effect under vertical earthquakes. Based on the stochastic vibration complex mode theory, the influence of the number of layers and the stiffness of the giant beam of the substructure with additional columns is further discussed by using the non-stationary ground motion model, and the results show that the influence of the number of layers of the substructure and the stiffness of the giant beam on the displacement and acceleration response of the MSCSS giant beam with additional columns is very significant.
