A model for simplified second order analysis of the double resistance to lateral force system is built on the basis to transform second order effect into negative stiffness.
为简化双重抗侧力体系二阶分析，将结构的二阶效应转化为结构的负刚度，从而建立分析模型。
However, the extent to which these factors affect the lateral resistance force of the wall differs. The wall aspect ratio and the stud space are the main factors that affect the lateral performance.
