钢结构各类构件抗力分项系数的研究

针对修订钢结构规范（GB 50017—2003）在2001系列规范条件下的可靠度指标偏低,尤其在遇风组合时,远低于规范规定的可靠度指标的情况,提出解决这些问题的办法,即针对不同的荷载组合采用不同的抗力分项系数。通过大量的计算,给出了修订规范下各结构构件的抗力分项系数取值。以供规范修订和工程应用时参考。

A Study of Resistance Partial Parameters of All Kinds of Components of Steel Structures

To revise values of reliability of Code for Design of Steel Structures （GB50017-2003） in 2001 serial codes on the low side, especially in case of meeting the wind to make up, reliability index is well below the required one, this article proposes the methods for these problems, namely adopting different resistance partial coefficient according to different load combination. Through a large amount of calculation, we have come up with different resistance partial coefficient values for every structural components of the devised Code for Design of Steel Structures for reference while the code is revised and used in practice.
