Investigation for resistance to torsion of the primary elements in the large miter gates

In this paper the theortical analyses and experimental studies on miter gates of large lock. The results obtained are presented are checked with the field test and the agreement are quite satisfactory. The distribution of deformation and stress of miter gates are acquires. The quantitative and qualitative analyses of the resistnce to torsion of the primary elements in the gate leaf are presented. The intrinsic characteristics of the atress increases in the vicinity if top and bottom pivots and in the zones near joints between the side column and diagonals are obtained.
