| Abstract: |
| An improved finite element-transfer matrk method is presented for the static analysis of the structures with large displacement in order to overcome the faults that FE-TM is generally ap-plied to structures with regular boundary. In this method,the propagation of round-offs errors oc-curing in recursive multiplication of the transfer and point matrices is avoided.A combined im-proved step incremental method with modified Newton- Raphson method is employed for the analysis of nonlinear problems. A program TNONDL-W1 is developed and numerical examples are presented to demonstrate the accuracy as well as the capability of the proposed method. |
