# 中部任意位置定向支承加固的压杆稳定性计算Stability Calculation of Long Column under Directional Support in Any Position of Central

Abstract: For enriching the research content about the stability of a long column and making it convenient in the engineering application, by using the initial parameters method, seven kinds of long column are strengthened by directional support in any position of central, and the unified deformation equa-tions and static force equilibrium equations are established. By the respective constraint conditions of deformation and static force, the characteristic equations of critical force are solved. By software, the approximate or accurate relationship between the factor of length of long column and the posi-tion of the central directional support are determined; at the same time, the best position of the central directional support and the minimum factor of length, and the worst position and the maximum factor of length are all determined. The result is verified according with theoretical expectation.
