［摘要］根据应变能相等的原则研究了一种沿竖向变刚度的结构连续化模型，推导了水平荷载作用下沿竖向变刚度的剪力墙结构各节点的内力和位移计算公式，改进了将单分段计算公式推导到多分段情况下高度累加的应用。通过算例分析并与有限元软件SAP 2000计算结果对比，验证了连续化模型及内力和位移计算公式的准确性和可靠性，为后续研究工作奠定基础。

Abstract:Under the principle of equal strain energy, the succession model with variable stiffness along height was given to calculate the inner force and displacement of each joint subjected to horizontal load, and the formula application of single segment to multiple segments along the model height was improved. The comparisons between the results of analysis example and SAP 2000 show that the succession model and formulas of calculating the inner force and displacement are  reliable and accurate, which could provide foundations for further research.

Keywords:shear wall structure; succession model; variable stiffness along height; horizontal load
