中文摘要：

针对考虑轴向力效应的弯剪型高层框架结构的弹塑性地震响应问题,研究转动惯性对高层框架结构层间剪力以及楼层屈服程度的影响。该文给出了考虑转动惯性的高层框架结构弹塑性分析的数值计算方法。对比了考虑和不考虑转动惯性时框架结构各层间剪力的最大值。针对不同塑性刚度系数情况,研究了考虑和不考虑转动惯性对楼层屈服的影响。通过是否考虑刚度系数中的轴向力,研究轴向力对结构层间剪力的影响。分析了竖向地震的作用力及楼层柱子的拉压状态。数值计算结果表明：转动惯性可造成高层框架结构底部楼层的层间剪力增大;竖向地震作用和结构自重对结构由水平地震作用产生的层间剪力影响很小;高层框架结构在强竖向地震作用下,其顶部附近楼层的柱子可出现受拉状态。

英文摘要：

The paper aims at investigating the effects of the rotary inertia in the elastoplastic seismic response and the spatial distributions of a yield storey for a high-rise framed structure.The shear-bending lollipop model with an axial force is used in this paper.A numerical method is presented for the elastoplastic analysis of the high-rise framed structure with the rotary inertia being considered.The maximum values of the inter-storey shear force obtained from considering the rotary inertia are compared with those without considering the rotary inertia of the structure.The spatial distributions of the yield storey are discussed for different plastic stiffness coefficients when the structure is subjected to horizontal and vertical seismic loads.The influences of the vertical force on the inter-storey shear force are studied.The vertical seismic load and the forces of the columns are analyzed.The numerical results demonstrate that the inter-storey shear force at the bottom of the high-rise framed structure increases when the rotary inertia is considered.The vertical seismic load and the structural dead load possess a little influence on the inter-storey shear force caused by horizontal seismic loading.The columns at the top part of the high-rise frame structure may be in the state of tension when the structure is subjected to a severe vertical seismic load.
