摘要：Based on the activation degree of the frame column stiffness, this paper studies the influence of the axial force area on the critical bearing capacity of the irregular frame and deduce some rules. Based on these rules, this paper corrects the critical bearing capacity of the regular frame and establishes the critical bearing capacity calculation method of the irregular frame. The axial force area ratio method can make up for the current codes can only calculate the critical force of the regular frame, which has great value in engineering application. Compared with the results of ANSYS, the axial force area ratio method has good precision. This method can consider the interaction between columns of the same story and the inter-story interaction.
