Abstract:  
As continual coming in my head beautiful picture of the bridge over river Parana in Argentina named General Belgrano with my impression about this heavy and so long steel construction made for transfer of big river. I always thinking how is installed huge steel construction and mass in one beautiful totality: The Bridge General Belgrano. Put in normal use and operation for traffic of people and merchandise is one moment for celebration with speeches and drink. At the end of such big job perhaps true impression would be if would be presented how much efforts and sweat followed this job. Each such job is observed and controlled regarding nominal tension and field point stresses of each steel items installed in construction, what is known of previous technical data of material. How is characteristics of depths of microcracks caused by fatigue of material.
