基于位移的建筑结构抗震设计(Displacement-Based Design,简称DBD)是最近几年抗震工程领域的热门课题,从此设计方法的原理出发,阐述了DBD的基本思想、特点、实现步骤,并就实现DBD比较方便有效的能力谱方法进行了详细的论述。最后指出了DBD仍然亟待解决的问题。
Displacement-Based Design (DBD) is a hot topic in the field of seismic engineering in recent years. Based on the principle of this design method, the basic idea, characteristics and implementation steps of DBD are described. More convenient and effective capacity spectrum method were discussed in detail. Finally pointed out that the DBD is still an urgent problem to be solved.
