不同地震水准下结构抗震设计分析方法及应用

ANALYSIS METHOD AND APPLICATION OF STRUCTURAL ASEISMIC DESIGN UNDER DIFFERENT SEISMIC LEVELS

对于建筑工程抗震设计,虽然规范有相应的要求,但设计师在具体工程中对于规范的理解与应用通常不够清晰。本研究基于某工程设计对抗震规范的应用,分析了抗震“三水准设防目标”和“两阶段设计方法”,即小震设计的具体内容和计算的目的。中震验算、大震验算的具体内容和目的及相关应用。经过对三水准下的结构抗震设计梳理,以期对我国抗震设计有较完整准确的把握。

For the seismic design of building engineering,although there are corresponding requirements in the code,designers'understanding and application of the code in specific projects are often not clear.Based on the application of the seismic code in an engineering design,this paper summarizes the"three-level fortification objective"and"two-stage design method",that is,the specific content and calculation purpose of small earthquake design.The specific content,purpose and related application of medium and large earthquake checking calculation.After sorting out the structural aseismic design under three levels,we hope to have a complete and accurate grasp of our country's aseismic design.
