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.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.
