PRACTICALITY VERIFICATION OF LARGE-SCALE FINITE ELEMENT METHOD ANALYSIS USING CONSTITUTIVE RELATIONS OF CONCRETE CONSIDERING SCALABILITY

Abstract

This paper tries to verificate the practicality of large-scale finite element method analysis using constitutive relations of concrete, which is reformed by a previous study considering calculation cost, with the objective of scalability. Since in the previous study they aimed to use the constitutive relation model with fracture analysis,we needt to extend the constitutive relation model to consider the effect of tension crack. This paper first shows the implemented algorithm. In the next step, seismic response analysis of a virtual nuclear power plant building is tried. At last, the practicality of large-sale finite element method analysis of RC structures is shown by the study on scalability of calculation.
