Y-type Eccentrically Braced Steel Frames-reinforced Concrete Core-tube Study On The Seismic Performance Of Structures

High-rise building is a product of social demands and technological progress andeconomic prosperity. With the use of high-rise buildings functional requirementsbecome more and more complex, the increase in high-rise buildings, is highly increasedin number at the same time, the structure form are changing. Hybrid structure that isresponsive to the changes that have developed one of the new structure. Hybridstructures this structure between the combination of different materials, is thesublimation of more great design ideas. Therefore, this structure is a much wider rangeof applications. China has built and under construction of high-rise buildings orhigh-rise building is the center of the most bracing instead of Y-type eccentricallybraced hybrid structures are relatively rare.In this paper, the steel frame-reinforced concrete core wall structure of Y-typeeccentrically braced steel frames was set on using general purpose structural analysissoftware MIDAS/Gen for failing to set the Y-type eccentrically braced, Y-typeeccentrically braced and change the layout outside of Y-type eccentrically braced steelframe-reinforced concrete core wall structure analysis of the seismic responsecharacteristics.Select a three Bay ten story frame structure is analyzed, the research on its seismicperformance under earthquake waves under rare earthquake.This paper established thelink beam model, analysis of shear yielding link beams in the rare earthquake under theaction of seismic waves and hysteretic behavior are, in order to understand the linkbeam under the action of earthquake damage mechanism and energy dissipationcapacity. Through the calculation, analysis of the factors in the seismic waves under rare earthquake effects of shear yielding link beam energy dissipation and the variation ofthe shear link beams, energy dissipation and energy beam section obtains the H sectionlength, web depth-thickness ratio and flange width-thickness ratio relationship, someadvice and Countermeasures the design shear yield of Y-type of energy dissipationbrace beam section.This article could serve as a similar study on structural system of research resultsand practical application reference.
