【 摘 要 】

When using Midas/civil solid element modeling to analyses a simple strengthening model by enlarging section method, it is found that the temperature stress of the model without implant reinforcing bars is very large under the overall temperature load, which is inconsistent with the actual engineering situation. When the model is implanted the reinforcing bars, the temperature stress generated by the overall temperature load becomes normal. It can be concluded that the defects of temperature stress anomalies caused by different linear expansion coefficients of different materials can be effectively corrected by implanting reinforcing bars in solid element models. When the defect of solid element model is corrected, its application prospects will become extremely broad, and it may eventually replace the calculation methods of internal force, stress and displacement provided by current engineering specifications.
