高层建筑钢结构实用概率极限状态设计

PRACTICAL DESIGN OF PROBABILISTIC LIMIT STATES FOR STEEL STRUCTURES OF TALL BUILDING

本文提出了高层钢结构的荷载组合系数与抗力分项系数,经计算满足可靠度要求。据此还提出了相应的厚板强度设计值的建议和高层钢结构的实用概率极限状态设计表达式,可作为普通钢结构设计规范GBJ17—88的补充和制订高层钢结构设计规程参考。

For design purposes, this paper presents performance coefficients for steel structures of tall building, and furthermore design values of strength of heavy plates. The calculated results show that suggested coefficients meet the requirements of probabilistic limit states design method. They can serve as a supplement to GBJ17-88 and the expression of limit states design provided in this paper is available for reference in compilation of concerned standard.
