With the rapid development of steel structure engineering in China, grid structure has been widely used. For the self-weight of space truss, the current regulations give the corresponding calculation formula, but in practical engineering applications, it is found that the calculation formula for column-supported space truss has poor adaptability. Therefore, in this paper, the adaptability of the formula is analyzed according to the current self-weight calculation formula for cylindrical point supported space truss, and the self-weight estimation of the space truss is revised on the basis of statistics and regression analysis. The formula modification can improve the applicability of the grid estimation formula, and also provide some reference for the revision of relevant codes and regulations.
