This paper introduces the endurance calculation method of seismic checking of existing large reinforced earthquakes in Japan based on the elasto-plastic theory, including the basic principles, methods and guidelines for endurance calculation, the influence of structural eccentricity and rigidity on endurance retention, The calculation of the retained horizontal endurance of each layer of the structure, the calculation of the structural characteristic coefficient that reflects the seismic behavior of the structure, and the steps and formulas of the structural endurance calculation method. And give a simple example. The above is conducive to China’s structural designers to learn more about Japan earthquake proofing of large reinforced concrete structures system and specific methods for the development of quantitative large-scale earthquake in China’s building structures provide a reference.
