Abstract:Dynamic elasto-plastic analysis technique is an important method commonly used in performance-based seismic design. Reasonable use of dynamic elasto-plastic analysis results in performance-based seismic design were discussed. Firstly, combining with relative theories, studies on methods of estimating the rationality of inner force and displacement results calculated by dynamic elasto-plastic analysis were conducted. On this basis, further discussion about problems involved in structural performance evaluation such as reasonable use methods of inner force results, criteria standards about structural components deformation limits, energy-based evaluation method, response of special seismic wave, judgement of potential failure mechanism and modes were went in depth into and specific application suggestions were given. In the end, a new conception of directly using inner force results calculated by dynamic elasto-plastic analysis into structural components design was put forward. The research  results  provide reference for development promotion of reasonable use of dynamic elasto-plastic analysis in performance-based seismic design.

Keywords:dynamic elasto-plastic analysis; performance-based seismic design; partial elasto-plastic analysis; seismic performance evaluation
