［摘要］設(shè)計(jì)軟件通常采用抗規(guī)方法或力學(xué)方法計(jì)算框架-剪力墻結(jié)構(gòu)中框架部分承擔(dān)的傾覆力矩，而采用這兩種方法得到的計(jì)算結(jié)果差別較大，因此對(duì)結(jié)構(gòu)設(shè)計(jì)的使用造成一定困擾。從框架-剪力墻結(jié)構(gòu)在水平荷載作用下的力學(xué)簡(jiǎn)圖出發(fā)，討論了兩種方法的差別，并采用典型框架-剪力墻結(jié)構(gòu)算例對(duì)兩種方法的計(jì)算結(jié)果進(jìn)行了對(duì)比分析。結(jié)果表明：抗規(guī)方法計(jì)算的結(jié)果反映了框架-剪力墻結(jié)構(gòu)總框架和總剪力墻的剛度比例關(guān)系，力學(xué)方法計(jì)算的結(jié)果除了能反映兩者的剛度比例關(guān)系外，還與連梁的剛度以及總框架相對(duì)于整體結(jié)構(gòu)的位置等因素有關(guān)，建議采用抗規(guī)方法計(jì)算框架-剪力墻結(jié)構(gòu)框架承擔(dān)的傾覆力矩。

Abstract:Two calculation methods of seismic code method and mechanics method are usually adopted by traditional design software to calculate overturning moment carried by frame part of frame-shear wall structure currently. The results of the two methods are often quite different, which cause some trouble to the structure design. Starting from the mechanical calculation diagram of frame-shear wall structure under horizontal loads, the differences of the two methods were discussed. Typical frame-shear wall structure examples were used for comparative analysis of the two methods. The results show that the calculation results of  the seismic code method reflect the stiffness ratio of total frame part and total shear wall part in frame-shear wall structure.  The calculation results of the mechanics method can not only reflect the stiffness ratio of total frame part and total shear wall part， but also  is related to the limited beams stiffness and the location of the frame part to whole structure. The seismic code method is recommended to calculate overturning moment carried by frame part of frame-shear wall structure.

Keywords:overturning moment carried by frame part; frame-shear wall structure; seismic code method; mechanics method
