钢结构各类构件抗力分项系数的研究

Study of Resistance Partial Parameters of all Kinds of Components of Steel Structures

针对修订钢结构规范(GB50017-2003)在2001系列规范条件下的可靠度指标偏低,尤其在遇风组合的情况下,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。

To revise values of reliability of Design code for steel structures（GB50017-2003） in 2001 serial codes on the low side, especially in case of meeting the wind to make up, the situation of the values of reliability that it is normal to be well below, this paper proposes the methods for solving these problems, namely adopt different resistance partial parameters to different loading making up . Through a large amount of calculation, resistance partial parameters of every structural oomponents of the edited Design code for the steel structures were proposed for reference while the code is revised and used in practice.
