STUDY ON DYNAMIC PROPERTIES OF FRAME-TUBE STEEL INTERLAYER STRUCTURE

摘要

The dynamic properties of frame-tube interlayer structure are studied in this paper. By means of three dimensional finite element analysis of a typical model, the dynamic properties and the rules of seismic response have been studied, and besides, the influences on main structure caused by stiffness changes of interlayer structure are carried on in parameter analysis. Preliminary results illustrate that steel interlayer structure has more shock absorption than reinforced concrete structure. Interlayer structure used steel has good a-seismatic behavior and it is a good prospect structure system for high-rise building.
