To use this program, users should : see the folder "exp". [1] prepare the "input.txt" file (the instruction is in "input_instruction.txt"). [2] compile and run the program in the same path with the "input.txt" file. [3] Analysis mode : 1-original Newmark approach; 2-Newmark-Predictor-Corrector approach. [4] The displacement and velocity of the mass point is recorded in "output_Newmark.txt" and "output_NPC.txt" file within the same folder.
The Newmark-Predictor-Corrector(NPC) time integration approach was added for SDOF problem. The original Newmark time integration approach was added for SDOF problem.
