The article presents the analysis of causes of accident of a water tower. Conducted examination of the structure showed the following: Water tower made in the form of welded sheet construction. Steel tank has a cylindrical shape, the diameter of the tank is 3020мм, cylindrical pole with a diameter of 1220mm and a height of 18m. The walls of the tower are made of sheet metal with a thickness of 4 mm, welded together back to back. On the East side there is a steel staircase made of 50х50х4 area with safety fence, made from steel strip -40х4. The lower part of the support diked soil with a height of 2.5 m. The tower has four stretch marks from the steel rope Ø12mm. The main causes of the accident was the deviation from a typical project in the manufacture of structural tower.

Discusses the calculation of a water tower Rozhnovskogo design, in the form of a welded sheet construction, structurally consisting of a tank of cylindrical shape with a conical bottom and a cylindrical roof and pillars. Performed creating finite element analysis model and the determination of the stresses in the tower elements with regard to the various features of the design, installation and operation of the facility. Discusses the local stability of the wall at the junction of cylindrical and conical parts. The necessity of the device the ribs in the conical part along the meridional direction and in the junction of annular ribs.
