Dynamic Behavior Analysis of Megaframe-Tube Suspension Damper Structural System

摘要

In this paper,the author combines suspension structure,mega-frame structure and tube structure with theory on structure controlling, brings forward new system of mega-frame-tube suspension damper structure. This kind of structure system using core-tube as means of vertical transportation, has bigger side stiffness. By setting damping controller between suspension floor and core-tube,structure is passively controlled by dead load of floor. This paper applies space-finite element analysis model, methods of random vibration analysis and time-history analysis to investigate the structure dynamic characteristic. Through calculation example, controlling effect on new system of mega-frame-tube suspension damper structure, important parameter and regularity that impact controlling effect are researched. Results indicate that the structure system has fine aseismic property. It is a new structure system in tall building simple to design,facile and having extensive prospect in application.
