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，如屈服强、延展、极限抗张强、硬、、冲击强等。

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

摘要采用非线全过程数值分析方法，计算了钢筋混凝土不等肢T形、L形和十字形柱截面模型在多种工况下截面率延比。
