The study presented a newly proposed mega-sub controlled structure system (MSCSS), connected to the design and building of high-rise structures, as enhanced durability and efficiency of mega-structural frames attracted the attention of researchers. In this article, a more reasonable and advanced mega-sub controlled structure model is designed and investigated under wind load. The complex model analysis theory is used to generate the equations of motion, the response spectrum (RS) expression, and the mean square response (MSR). The dynamic features that influence the control response of MSCSS, such as relative stiffness ratio (RD) and relative mass ratio (MR) between the mega-frame and substructure, are defined and investigated. The result showed that the displacement effectiveness is highly effective at low stiffness ratios, with a sharp decrease in maximum displacement observed when RD is less than 0.17 (RD 0.6. Furthermore, the study reveals that increasing the relative mass ratio obviously improves both displacement and acceleration control effectiveness at fixed RD = 0.3.
