To solve this problem, it is especially important to select and take reasonable over-reinforced measures. Based on the simplified model of coupled shear wall structure, this paper uses the approximate theory to for analysis, fully demonstrating influence of coupling beam rigidity and shear wall rigidity on structural endogenous force distribution as well as their correlation and interaction. In the last section, the paper uses the calculation theory on shear wall structure to analyze by engineering instances over-reinforced measures.
