摘　　要：结合工程设计，分析了高层轻砼框支剪力墙结构的变形特点，导出了考虑边缘构件砼及钢筋作用的结构构件屈服强度和极限强度的计算公式，编制了计算程序．对实际结构进行了多波输入地震反应的弹性和弹塑性时程计算，论述了地震波、结构构件的弹性参数等因素对变形分析的影响．还推导建立了用控制结构薄弱层层间变位方法确定落地剪力墙合理数量和框支柱截面尺寸的简化计算方法，提出了结构层刚度和层抗剪屈服强度计算公式，并通过实际工程二次设计的变形控制与验算，考察了本文方法的合理性，表明计算精度满足工程设计的需要．In this paper, combined with a real engineering design, the deformation characteristic of lightweight reinforced concrete high-rise frame-supported shear wall structure under earthquake is analysed. The calculation formula and computer program of structural elastoplastic parameters (such as: yield strength, ultimate strength) are presented, which are used whenever concrete and steel effect of edge components are taken into account. The seismic response of a real engineering project is calculated by the time-history method, and effects of many factors (such as: earthquake acceleration records, p-Detle effect and calculation method of structural elastoplastic parameters etc. ) on the deformation are analysed. The simple method of fixing the reasonable number of shear walls and frame-supported column size is set up by controlling the displacement of structural weak story, and the calculation of structural story stiffness as well as story sheal yield strength are presented. On the second phase of seismic design, combined with the deformation
