Japan Atomic Energy Agency has been developing the three-dimensional virtual shaking table for earthquake-resistant evaluations in the atomic energy facilities. It is to realize an earthquake proofing reliability examination by analyzing the earthquake-resistant of the large structure on a computer. This is the trial that is going to realize a virtual shaking table examination such as difficult size of the original structures or nuclear power generation facilities while driving on a computer. Authors develop the structure analysis cord of the assembling structure so called FIESTA (Finite Element Structural Analysis for Assembly) as one of the core functions. This is the details analytical method that paid its attention to the behavior between the part of the assembling structure as one means to perform the earthquake-resistant evaluations for such as atomic energy facilities. In this report, it is reported the way of time history response analysis by assembly structural analysis.

Quality Assurance is an issue for computational science and engineering. It is well discussed in verification and validation for Simulation. In finite element analysis, it is a problem whether the finite element discretization is appropriate or not. Also, algorithmic choice prepared variously by the recent R&D discipline that become the problem which one to take. An experiment was performed for the static analysis and natural frequency analysis to confirm how uncertainty is revealed. As a result, by means to compare accuracy of the calculation precision that utilized a parallel environment, the numerical experiment reconfirmed that the estimate of the calculation solution was possible.

Facilities in nuclear industry are known as large structures consisting of components more than 10 million. A method to analyze an assembly by gathering its components data has been introduced. This paper discusses how to understand certainty in results of assembly structural analysis. Numerical results are discussed with K, computer.
