砼L形双偏压柱正截面强度的近似相关方程

Approximate correlation equations for the strength of normal cross section of L-shaped R. C. Columns subjected to biaxialy eccentric compressive loadings

根据L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L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 real correlation curves for the strength ofcross section of L-shaped R C. columns and using the curve-fitting method, an approximatecorrelation equation was established. which has a very simple form and is very close to realcorrelation curves, The approximate conclation equation presented is easy to be used and hashigh accuracy for design purpose, and can be considered as a comparatively ideal restrainedequation for the bearing capacity of L-shaped R. C. Columns Subjected to Biaxialy coocnticcompressive loadings.
