摘要
本文利用MIDAS建立箱形杆件三维模型,梳理了采用MIDAS进行屈曲分析的流程和存在的注意事项,并将MIDAS计算的临界应力与公式理论值进行对比,验证采用MIDAS建模的正确性。同时,结合具体实例进行分析,结果发现,采用MIDAS计算得到的临界荷载大于理论值,且比理论值大3.6%,在工程合理范围内,为今后在工程中采用MIDAS对结构进行屈曲分析提供了依据。
In this paper,a three-dimensional model of box-shaped members is built by MIDAS,and the process of buckling analysis using by MIDAS and the existing precautions are sorted out.And the critical stress calculated by MIDAS is compared with the theoretical value of the formula,which can verify the correctness of MIDAS modeling.At the same time,combined with specific examples,the results show that the critical load calculated by MIDAS is greater than the theoretical value,which is 3.6%that is within the reasonable range of the project.It provides a basis for the future buckling analysis of the structure by using MIDAS in the project.
