Belikova N. Carrying capacity of reinforced concrete railway poles after renovation and strengthening

Object the ferroconcrete supports of overhead electric transport power line; purpose - development of the procedure of the estimation of the bearing capacity and strengthening and of repairing the ferroconcrete supports of overhead electric transport power line to the bearing capacity, is developed the new construction of the support of overhead electric transport power line - the steel tube, filled with concrete, is developed the method of strengthening the ferroconcrete supports of overhead electric transport power line with the aid of the steel rings, placed on the height, is developed the task of calculating the steel-concrete support to the power and temperature actions; results - calculation procedure and methods of strengthening, with the aid of the steel cartridge clip make it possible to prolong the period of the service of the existing ferroconcrete supports and to increase the reliability of the newly projected supports; the sphere of use - design and the operation of the ferroconcrete supports of overhead electric transport power line.
