Abstract: A pre-post process program developed for importing ETABS text data to PERFORM-3D binaries file, PERFORM-3D model conversion parameters setting and method of the calculation of the plastic hinge is introduced in this paper , the pre-post process program developed can make the PERFORM-3D more convenient for elastic-plastic analysis of which applied to complex structures. Finally ,a case study Elastic-plastic time-history analysis under rare earthquake performed by Perform-3d shows the application of the pre-post process program.
Keywords: pre-post process program;plastic hinge;Elastic-plastic time-history analysis;PERFORM-3D
