Reinforced Concrete Giant - Sub Controlled On Seismic Performance Of Numerical Analysis

During the last few years,Mega-Sub Controlled System,one of the new-style tall structure system,is attached importance by more and more engineers and scholars. Mega-Sub Controlled System is firstly brought forward by American scholar MARIA Q.Feng .Afterward, some scholars drew amelioration to i.t,such as seting vibration isolating device, energy-dissipating damper, or additive pillar between the mega frame and the sub frame, which be likely to get better frequency modulation and better libration-controlling performance. At the present time ,the central studying task about the Mega-Sub Controlled System is analyzing the validity ,the feasibility,and its economic benefit .Based on the basic theory of Mega-Sub Controlled System, a framework project is built,and a three dimensional parametrization finite element model is set up in this paper,some subroutines are programmed in APDL for the modal analysis, spectral analysis, power spectral density analysis and time-history analysis.with these subroutine,a all-sided aseismatic performance analysis of the Mega-Sub Controlled System is caught through. By comparing with common frame construction,the result suggested: Mega-Sub Controlled System markedly reduce the velocity and acceleration response of the sub frame.in addition,the method to analyse the aseismatic performance of tall structure with ANSYS software is also valuable to similar project.
