ABSTRACT: Due to the high seismic site conditions, the nonlinear seismic SSI analysis is required in Japan for the design basis analyses on the NPP structures In many other countries including US, the nonlinear seismic SSI analysis is not required for the design basis analyses by current regulations, except for some special design detailed aspects related to foundation soil interface modeling that need additional research studies. This special session introduces a practical engineering approach for nuclear industry for performing nonlinear seismic SSI analysis of buildings The introduced SSI approach implementation follows the Japanese nonlinear structure modeling and seismic analysis practice for reinforced concrete buildings, and it further extends it to detailed 3 DFEM SSI models. It has a robust engineering foundation, i n compliance with Japan standards (JEAC 4601 2015 JEAC 4618 2009 AIJ RC 2018 and US standards (ACI 318 19 ACI 349 14 ASCE 4 16 ASCE 43 19 for RC and SC wall modeling. The
introduced approach is based on a hybrid SSI approach that uses an iterative scheme which couples the equivalent linear complex frequency SASSI analysis with the nonlinear time domain RC/SC structure analysis. The iterative approach is fast converging in few SSI restart iterations, being attractive to industry due to its accuracy, convenience and affordability, plus its close compliance with standard and regulatory requirements. This special session presents a set of two papers that introduces key modeling and implementation aspects of SSI approach, and another set of three papers that presents few independent verification and validation studies performed by Japan industry, universities and nuclear agency.
