《混凝土结构加固设计规范》第8.2.2条的公式仅用于单向偏压作用下矩形截面正截面承载力计算,对于双向偏压角柱计算方法有必要作进一步的研究。通过一个工程实例,采用有限元的方法,比较详细和全面地对双向偏压作用下外粘型钢加固角柱进行了深入的计算和探讨。
The formula of Article 8.2.2 of “Code for Design of Reinforced Concrete Structures” is only used for calculation of the normal section bearing capacity of rectangular section under unidirectional bias. Further study on the calculation method of biaxially-biased angular columns is needed. Through a project example, finite element method is used to calculate and discuss deeply and comprehensively the reinforcement columns with external viscous steel under bidirectional bias.
