Abstract: The software, PERFORM-3D, is used for the nonlinear analysis and performance evaluation of the complex and out-of-codes structural systems. In this paper, elements for beam-column and shear-wall were firstly analyzed. The case study shows that numerical simulation accuracy of PERFORM-3D is good enough with excellent efficiency and stability. Performance evaluation is the key function of PERFORM-3D, and performance index and user-defined level, which are for the material, structural member and story, were introduced.  Finally, the performance evaluation system was analyzed and demonstrated by the case study.

Keywords: PERFORM-3D; structural seisnuc-performance; performance evaluation
