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

［提］结构影响系数主延性折减系数和超强系数。

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

摘采用非线性全过程数值分析方法，计了钢筋混凝土不等肢T形、L形和十字形柱截模型在多种工况下的截延性比。

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，如屈服强度、延展度、极限抗张强度、硬度、弯性、冲击强度等。
