（中國建筑科學(xué)研究院深圳分院 深圳 518028）[提要] 通過算例分析比較，對高位轉(zhuǎn)換層結(jié)構(gòu)的抗震性能和受力特點等進行了研究。結(jié)果表明，當(dāng)轉(zhuǎn)換層位置逐漸上移時，由于轉(zhuǎn)換層質(zhì)量較大，結(jié)構(gòu)的振型地震作用在轉(zhuǎn)換層處有明顯增大，但結(jié)構(gòu)周期及振型僅有一些量的變化，樓層的地震剪力和彎矩在轉(zhuǎn)換層以下樓層也有所增大，結(jié)構(gòu)抗震計算時，振型數(shù)應(yīng)適當(dāng)增加。

It shows with the height of transfer floor increasing, the mode seismic action at transfer floor is increased evidently because of the greater mass of the transfer floor, but the natural period and vibration mode of the whole structure is changed a little,and the seismic shear and moment of stories below transfer floor are increased. It is pointed out that the mode number needs to be added in analyzing seismic action as well as internal forces of the structural components.
