双空间钢构架混凝土偏压短柱承载力计算方法

Calculation method of bearing capacity of concrete short columns with biaxial compression of double space steel frame

本文所研究的双空间钢构架混凝土柱是由内外空间钢构架组成,即在空间钢构架混凝土短柱中内埋空间钢构架,形成一种对混凝土有着两重约束的双空间钢构架混凝土组合柱。为了探究这种组合柱的偏心受压承载力计算方法,以试验研究为基础,建立相关的N-M偏心受压方程。计算后得出的方程计算值与试验值较为吻合,验证了Nu-Mu偏心受压方程计算方法的可行性。

The double space steel frame concrete column studied in this paper is composed of internal and external space steel frame,that is,the space steel frame is embedded in the short column of space steel frame concrete,forming a double space steel frame concrete composite column with double constraints on concrete.In order to explore the calculation method of eccentrically loaded capacity of this kind of composite column,the relevant N-M eccentrically loaded equation is established based on the experimental study.The calculated value of the equation is in good agreement with the test value,which proves the feasibility of the calculation method of Nu Mu eccentric compression equation.
