根据十形截面双向偏心受压柱正截面强度相关曲线的特点 ,采用曲线拟合方法 ,构造出了一个可以逼近“真实相关曲线”的相关方程———近似相关方程 .该方程形式简单 ,便于工程应用且具有很高的计算精度 ,是十形截面钢筋砼双向偏心受压柱较为理想的承载能力约束方程 .
According to the characteristics of the cross-section intensity curve of the cross-section of the ten-shaped cross-section biaxial eccentric compressive column, a curve fitting method was used to construct a correlation equation that can approximate the “true correlation curve”—the approximate correlation equation. The equation is simple and convenient. It is an ideal bearing capacity constraint equation for the ten-shaped cross-section reinforced concrete and biaxially eccentric compression columns.
