| 摘 要： | 将角钢等效成简单板材，通过分析其屈曲／后屈曲来等效研究角钢的局部屈曲／后屈曲．采用ANSYS严格按照角型材实际尺寸建立三维实体模型，并进行屈曲／后屈曲数值模拟．三维有限元解与理论等效结果符合良好，充分说明该等效分析的正确性和适用性．

| Abstract: | The angle steel is equivalent to a simple plate and the local buckling/post buckling of angle steel is analyzed by the equivalent analysis on the buckling/post buckling of the simple plate. ANSYS is used to build a 3D solid model according to the actual size of angle profile and the buckling/post buckling is numerically simulated. The 3D finite element solutions are in good consistency with the theoretical solutions, which demonstrates the correctness and applicability of the equivalent analysis. |
