摘要
为确保高层框架-剪力墙结构多道抗震防线性能的合理实现,《高层建筑混凝土结构技术规程JGJ 3-2002》修改了框架-剪力墙结构中框架柱地震剪力的调整方法;该文在参考文献《高层框-剪结构中框架地震内力的确定》的研究基础上,提出一种基于结构变形指标并考虑剪力墙刚度退化的框架-剪力墙混凝土结构框架地震剪力的分段实用计算方法;通过工程实例把该文方法与《高层建筑混凝土结构技术规程JGJ 3-2002》方法的计算结果进行了比较和分析;实例表明:《高层建筑混凝土结构技术规程JGJ 3-2002》的调整方法是十分必要的,该文方法可作为规范补充和完善的重要参考。
In order to insure the multiple aseismic fortification line performance for a frame-shear wall structure in tall buildings,in the ＂JGJ 3-2002,Technical specification for concrete high-rise building＂ the calculation method for the seismic shearing force of frame columns of a frame-shear wall structure has been modified.Based on the ＂Determination of seismic forces acting on frame in high-rise frame-shear wall structures＂ study,in this paper a practical approach in segments for the seismic shearing force of a frame-shear wall structure is finally presented,which is based on a deformation index,and at the same time,the stiffness degeneration on the shear wall is taken into account.Furthermore,this method is compared with the former by the result of an example.The results indicate that this method is necessary and available.This method supplies an important reference for the supplement of design codes.
