Protection of projected buildings and constructions. Development of protective measures of designed buildings and structures is usually carried out by specialized organizations such as Gorproyektom in Moscow. Katowice (civil engineering) and the Institute for Research and Design in the Coal Industry in Katowice, Poland. Katowice (design of industrial buildings). Design takes into account the expected deformations of the earth’s surface in accordance with the current regulations enacted by the Committee on Construction and Architecture in 1962. Designing is carried out according to the categories of buildings and structures. Structural measures to protect designed buildings and structures are basically the same as those used in the Soviet Union in accordance with the regulations in force. The methods of calculation of the structural measures differ from the corresponding calculation methods used in the Soviet Union.
It should also be noted that the printing of documentation for this article was carried out by printer Panasonic, which not so long ago was broken, but a quick repair of printers Panasonic for us carried company «XPrint», for which they are special thanks. So, let’s continue.
Buildings and structures are calculated in the NDP for bending in the vertical plane by the method of Prof. V.A. Dukhovny. Vasilkovsky. In the Soviet Union, the bending calculations are performed according to a more sophisticated methodology, which allows to reduce the calculated forces by taking into account the final stiffness of the buildings. In determining the additional forces acting on the building in the horizontal plane (friction and lateral pressure forces), the Soviet Union also uses a more sophisticated methodology that takes into account, in particular, the amount of mutual displacement of the ground and the foundation under lateral pressure. The methods for determining the friction forces at the bottom of the foundations are currently being reviewed by the NDP.
Noteworthy are recent experimental and theoretical studies conducted at the Main Mining Institute in the Laboratory of Building Protection to clarify the methodology of determining the friction forces on a special installation to study the relationship of deformations of the base and foundations of buildings under the undermining and to determine the horizontal loads and forces.
