强度折减系数研究综述

The Review of Strength Reduction Factor

强度折减系数既是基于强度抗震设计的关键,又是基于性态抗震设计的基础.本文以近十年来国内外的相关研究成果为基础,分析总结了对强度折减系数影响因素的研究进展,并对尚需进一步研究的问题进行归纳.

Strength reduction factor is not only the key to strength based design method, but also the basis of per- formance based seismic design method. By reviewing the domestic and foreign research achievements of recent ten years, this paper summarizes the research progress of various influencing factors on strength reduction factor, and concludes existing problems that need further investigation.
