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

［提］结构影响系数主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.

由机械试验决定特性，如屈服强度、延展度、极限抗张强度、硬度、弯曲性、冲击强度等。

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

摘线性全过程数值分析方法，计算了钢筋混凝土不等肢T、L和十字柱截面模型在多种工况下截面曲率延性比。
