The task of identification of defects in rods with different variants of fastening. In the basis of lies method parameter identification based on an analysis of the frequencies and parameters of natural modes of the structure. Built model of the rod design has defects fluctuations, using finite element of the complex

Cracking of reinforced-concrete elements with holes is examined. Comparison of theoretical and experiment moments of crack’s formation during torsion, and during intensive torsion with twist. Formula for practical calculations of cracking of reinforced-concrete elements with holes during torsion and formula for estimate of cracking of reinforced-concrete elements with holes during intensive torsion with twist is suggested.
