OpenSees Concrete04 Material Test

Concrete04受压部分的包络线采用Popovics (1973) 提出的单调荷载下的应力—应变关系，并根据Karsan-Jirsa加卸载准则确定其加卸载刚度（线性）；受拉部分的包络线由线性上升段和指数下降段组成，其加卸载与再加载刚度取其与原点的割线刚度。(Concrete is a uniaxial Popovics concrete material object with degraded linear unloading/reloading stiffness according to the work of Karsan-Jirsa and tensile strength with exponential decay.)

OpenSees Concrete02 Material Test

OpenSees Concrete02 Material Test.Concrete02与Concrete01相比，考虑了混凝土的受拉力学性能（线性）。在受压方面，与Concrete01相同的是，考虑了混凝土随着残余应变的增大，加、卸载的刚度发生退化；不同的是，Concrete02在同一卸载过程，卸载的刚度也在发生退化。

OpenSees Steel01 Material Test

OpenSees Steel01 Material Test. Steel01是OpenSees中最简单的单轴钢筋材料，骨架曲线为二折线，默认为随动强化，可以考虑分别考虑拉压方向的各向同性强化。（Steel01 a uniaxial bilinear steel material object with kinematic hardening and optional isotropic hardening described by a non-linear evolution equation. ）
