Abstract

This article calculates the effective length coefficient of frame columns by orthogonal decomposition of the linear stiffness of beams. Meanwhile, a simplified model was established using SAP2000 finite element software, and effective length factors in the x and y directions were calculated using the Euler formula. By comparing effective length factors calculated by manual calculation, Euler inverse calculation, and SAP2000 methods, it is found that the three calculation results for the frame structure with lateral displacement are consistent. However, the effective length factor calculated by Euler's formula in reverse ignores the coupling effect between constraints, resulting in a greater result than the other two calculation methods, and the manually calculated effective length factor is the smallest. This method can be used as a reference for determining the calculated length coefficient of the frame columns in the main beam plane oblique steel frame structure.
