reinforcing steel reinforcement

Problems are often occurred: cross-section of frame columns depends upon the limit of axial compressive ratio, the constructional reinforcement ratio becomes the ratio of longitudinal reinforcing steel bar of frame columns, such problems are not reasonable.

经常出现的情况是：框架柱的断面由轴压比限值确定，而框架柱的配筋由构造配筋率决定，这其中存在着不合理的地方。

The uniform elongation is the characteristic strain of reinforcement steel at maximum force in simple tension test, it is an important indicator to reflect the ductility of reinforcing steel, and directly affects the seismic behavior of structure.

钢筋在拉伸试验中，达到最大作用力时对应的总伸长率为均匀伸长率，它是反映钢筋延性的重要指标，直接关系到结构的抗震性能。

This model transacts and calculates pull and press section of reinforcement concrete by different methods: the reinforcing steel bar element model is adopted at pull section and the reinforced concrete enblock model is adopted at press section.

该模型用不同方法处理计算钢筋混凝土拉区和压区：拉区钢筋采用杆件单元模型，压区钢筋混凝土则采用整体式模型。
