METHOD FOR ANALYZING NON-LINEAR TIME AREA IN GROUND-STRUCTURE CORRELATION

摘要

PURPOSE: A method for analyzing a non-linear time area in ground-structure correlation is provided to be capable of overcoming a time area analysis function as the problems of existing frequency slave precise ground-structure correlation analysis using ANSYS or ABAQUS. CONSTITUTION: First, the time history of response against weighting load on a remote ground including the ground and the structure is obtained by using codes such as FLUSH, CLASSI, SASSI, HASSI, KIESSI of a dynamic analysis technique providing accurate solutions in considering the correlation of ground-structure. Then, an accurate time area analysis and a non-linear response analysis are performed by applying load to a boundary between a close ground including simulated ground and structure and the remote ground using ANSYS OR ABAQUS of a general finite element analyzing program which can simultaneously consider both the time area analysis and non-linear analysis.
