摘要：It is analyzed and tested the substitution of triangular section columns for single steel outgoing line columns in the 500kV fully united framework based on the design, test and analysis with 18 specimens of single steel pipe. The theoretical calculation method of bearing capacity is put forward by analyzing the design theory. Through the experimental analysis and research, the computational model with bottom fixed, middle hinged and top hinged is obtained, which is consistent with theoretical values, thus providing valuable reference conclusions for the revision of the specification. It provides meaningful theoretical and experimental data for the analysis and calculation of substitution of single steel pipe outgoing line column for the original triangular section outgoing line column for the 500kV fully united framework.
