[试验][研究][小工具][编程] YPD:Yielding Point & Ductility [等效屈服点和延性计算]
软件根据构件或结构的力-位移骨架曲线计算的等效屈服变形、极限变形和延性系数。软件提供了3种常用的等效屈服位移计算方法：几何作图法、等能量法、R.Park法。方便研究而编写的小工具，特别适合于做实验研究的同学。This program is used for evaluation of yield deformation , ultimate deformation and ductility factor of structures and structural assemblages from laboratory testing , based on the force-displacement backbone curve. Three commonly used methods for estimating the yield deformation are provided by the program. These includes : Geometric Graphic Method , Equivalent Elasto-Plastic Energy Method, R.Park Method.It’s a simple-to-use program.
