该代码将提取抗震试验的滞回曲线，形成骨架曲线，大大简化了数据的处理过程。可将其添加到MATLAB 的APP 中直接使用。还有几个命令流是ANSYS中提取结构刚度矩阵的代码。(This code will extract the hysteresis curve of the seismic test to form a skeleton curve, which greatly simplifies the data processing process. It can be added to MATLAB's APP and used directly. There are also several command streams to extract the structural rigidity matrix code in ANSYS.)
