摘要
简要介绍了美国混凝土协会ACI318—2002规范有关抗弯构件设计的统一方法,并就梁和柱的承载力折减系数对2002规范和1999规范作了对比。结果显示两者间存在着较大的差别。采用统一设计方法的2002规范,尽管计算量有所增加,但总的来说理论上更加合理,对我国设计规范的修订有一定借鉴意义。
The unified approach of flexural design specified is introduced in the Building Code Requirements for Structural Concrete（ACI318-02） and Commentary （ACI318R-02）. Strength reduction factors specified in the 2002 code and the 1999 code are compared analytically using typical design examples of beams and columns. It is found that significant difference exits between the two versions. The rational for the unified approach is apparent and may shed some lights for the future changes of the Chinese design codes.
