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

［提要］结构影响要包括延性折减和超强。

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

由机械试验决定的特性，如屈服强、延展、极限抗张强、硬、弯曲性、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.

摘要采用非线性全过程值分析方法，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的截面曲率延性比。
