This paper presents the framework for a performance-based seismic assessment of coupled soil-structure-fluid systems via integrated 3D finite element (FE) analysis. The proposed strain-based performance approach reduces the conservatism and uncertainty associated with...

The standard assumption of modelling the vertical component by vertically propagating P waves underestimates the spatial variability of the vertical ground motion over the dimension of the foundation of large structures, which can lead to very large vertical floor...

Introduction Currently, spent nuclear fuel (SNF) is stored in onsite independent spent fuel storage installations (ISFSIs), which are dry storage facilities, at 55 nuclear power plant sites. Because the SNF will be stored at ISFSIs for an extended period of time,...

Steel-plate composite (SC) structures consist of infilled concrete between steel faceplates with shear ties connecting the front and back faceplates. Shear ties can be made of bars, rebars, plates, or steel shapes. Currently, there is a tendency in the nuclear...

Seismic analysis, including the consideration of soil-structure interaction (SSI), is an important and required step in the design and licensing of nuclear power plant structures, systems, and components (SSCs) that are important to safety. Historically, the SSI...
