| Abstract: | Under the action of shear force and torsion, the calculation of shear fluid in thin wall multi boxes steel sections can be attributed to the solution of a group of linear equations. The coefficient matrix of the equations is a kind of positive matrix. It can be solved by square root method. The time consumed in square root method is half of that in Gaussian elimination method. |

| Keywords: | shear fluid positive matrix triangle decomposition square root method |
