节段预制拼装梁抗震性能的有限元分析研究进展

Research Progress of FEA on Seismic Performance of Precast Segment Beam

主梁的节段预制拼装技术现在得到广泛运用,但是由于在其抗震性能研究上目前仍有欠缺,限制了该工法在高地震危险区的进一步推广。讨论了目前国内外对节段预制拼装主梁抗震性能研究的试验和数值分析成果,着重阐述有限元分析研究的进展,指出进一步需要研究的问题。

Precast segment bridge construction has been widely used in recent years.However,the lack of research on seismic performance of precast segment beams has restricted the usage of this method.This article summarizes the experimental results of seismic performance of precast segmental beam.In addition this article promotes the development of finite element analysis and includes a discussion of the existing flaws which may facilitate the expansion of future research.
