Abstract:The structural influencing coefficient includes ductility reduction factor and overstrength factor.

［提要］结构影响系数主要包括延性折减系数和超强系数。

Properties determined by mechanical testing, such as yield strength, ductility, ultimate tensile strength, hardness, bendability, impact strength, etc.

试验决定的特性，如屈服强、延展、极限抗张强、硬、弯曲性、冲击强。

The cross-section curvature ductility ratio for R.C inequiaxial T-shaped, L-shaped and cress-shaped columns is calculated by numerical method.

要采用非线性全过程数值分析方法，计算了钢筋混凝土不肢T形、L形和十字形柱截面模型在多种工况下的截面曲率延性比。
