摘要
针对钢筋混凝土框筒夹层结构,运用ANSY S软件,建立三维有限元模型进行了振型分析,得出了该结构的自振特性;分别采用振型分解反应谱法和非线性时程分析法进行了结构在罕遇地震作用下的地震反应分析。研究结果表明夹层结构采用钢结构比采用钢筋混凝土结构具有减震作用,采用钢夹层结构具有良好的抗震性能,是一种具有应用前景的高层结构体系。
According to the reinforced concrete framed tube building,a three-dimension FEM model is built up by using software ANSYS.The free-vibration characteristic of the structure is obtained by performing vibration mode analysis.Moreover,seismic response analysis of this building is carried out in mode-superposition response spectrum method and dynamic time history analysis method..Preliminary results illustrate that steel interlayer structure has more shock absorption than reinforced concrete structure.Interlayer structure used steel has good aseismatic behavior and it is a good prospect structure system of high-rise building.
