- Synopsis
- An expanded version of the “Seismic Performance Verification Guidelines for RC Underground Structures in Nuclear Power Plants” was published by the Japan Society of Civil Engineers in October 2021 for the purpose of advancing technology for the verification of the seismic performance of reinforced concrete underground structures. These guidelines systematically organize the latest knowledge on performance verification methods for underground structures, expanding on seismic response evaluation methods for structures in dense liquefied ground, raising the accuracy of the seismic performance verification method using 3D nonlinear analysis, and adding a new method for evaluating the effects of fault displacement. This paper outlines the expanded content of these guidelines.
