［摘要］动力弹塑性分析技术是目前基于性能的抗震设计经常采用的重要分析手段，主要针对动力弹塑性分析结果在设计中的合理使用问题展开讨论。首先结合理论研究了如何对计算所得内力和位移结果进行合理性判断；在此基础上对结构性能评估中涉及到的内力结果合理使用方法、构件变形限值判断标准、能量评估方法、特殊地震波响应、结构潜在破坏机制和破坏模式的判断等问题进行了深入讨论，并分别给出了具体应用建议；最后提出一种直接采用弹塑性分析所得内力结果进行构件设计的新思路。研究成果为进一步推进动力弹塑性分析方法在结构性能抗震设计中的合理应用提供借鉴。

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.
