IV - Nonlinear RT-Frame2D plus Physical MR Damper Real-time Hybrid Simulation

The last validation procedure features RT-Frame2D nonlinear elements in the modeled MRF structure. Only phase I and II of RTHS are conducted and compared in this test matrix. The beam moment-curvature relationships are characterized by three different models that are linear, bilinear and tri-linear kinematic hardening rules, respectively. Columns are modeled to be linear elastic and the beam column joints are characterized by the linear panel zone model. The mass and damping assumption follows the multi-floors RTHS experiment. The El-Centro earthquake is scaled to be 0.7 of the original intensity for all tests.本次最终验证流程在建模的MRF（弯矩抵抗框架，Moment Resisting Frame）结构中采用了RT-Frame2D非线性单元。本次试验矩阵仅开展并对比了RTHS（实时混合试验，Real-Time Hybrid Simulation）的第一、二阶段内容。梁的弯矩-曲率关系分别通过线性、双线性及三线性运动硬化准则三类不同模型进行表征。柱采用线弹性建模，梁柱节点则采用线性节点域模型进行表征。质量与阻尼的假设遵循多层RTHS试验的相关设定。所有试验均将埃尔森特罗地震的激励烈度缩放至原烈度的0.7倍。
