摘　　要：运用SATWE和ETABS程序对框架-核心筒结构采用3种不同连梁设计方法(强连梁、弱连梁和双连梁)时的结构整体进行了地震反应分析,得到了周期、振型、层间位移数值及基底剪力等结构动力特性随连梁截面变化的规律.从核心筒剪力墙空间整截面共同工作性能、核心筒所承担的地震倾覆力矩、核心筒抗扭刚度及连梁具有良好耗能性能等4个方面综合分析,得出剪力墙连梁应优先采用强连梁和双连梁,一般不应采用弱连梁,并给出了确定合理连梁截面尺寸的一般设计原则.Dynamical characters of frame-core wall structure designed by different methods （stiffening coupling beam; feebleness coupling beam; pair of coupling beams） were analyzed by using SATWE and ETABS software. The change disciplinarian of structure dynamical properties were obtained, including mode, natural period, interlayer displacement and basic shear along with coupling beams section variety. Based on several aspects of frameore wall structure as follows： the whole section work performance, overturning moment and tensional stiffness under earthquake, and energy-dissipation properties of coupling beams, stiffening coupling beam and pair of coupling beams design method should be adopted preferentially. Feebleness coupling beam design method should not be adopted generally. The principles for determining rational coupling beams section was given.
