The plasticity/creep/connector friction algorithm did not converge at 1 points The strain increment has exceeded fifty times the strain to cause first yield at 449 points The strain increment is so large that the program will not attempt the plasticity calculation at 1 points The plasticity/creep/connector friction algorithm did not converge at 56 points 鋼混組合梁運用cdp模型就出現(xiàn)這種情況，大概是什么原因??求助大佬
