Mathematical model of asphalf carpet wavefornation and example of calculation bearing capacity of flu top layer of asphalt pavement against wave formation on areas of heavy braking traffic was described.
The results are given on the basis of an experimental research on firmness and deformability of normal sections of concrete beams reinforced with frameless reinforcement and rod reinforcement class A400C without prestressing. These experiments and comparing them with calculations according to current regulations give an opportunity to assess the convergence of the results and draw conclusions about the possibility of rational design of ceramic block bending elements with double reinforcement in the area of the normal forces.
In this paper for calculation of reinforced concrete columns strengthened with carbon laminate with suggestions based on the method of calculation according to the recommendations NIISK and Sika on the basis of deformation model calculation according to regulations . To determine the additional eccentricity introduced by bending flexibility factor, which is derived using in Eurocode 2. The algorithm for calculating strengthened at the primary level loading columns.
