Stress fields in steel bridges

The paper deals with steel structures of road bridges. Multidimensional dynamic stress diagrams are suggested for analysis and quantitative conclusions presented the trouble-free operation complex loaded structures. describes spatial distribution mechanical stresses in buildings based on obtained data under various loads statistical different points zones object. Acoustic measurements carried out during bridge operation, mathematical distributions all measured points. It is shown that determining entire array loads, a criterion can be identified elements structure as whole. Mathematical or parameter Χ 2 introduced. found real three-dimensional clearly units parts findings confirm proposed hypothesis about possibility such description. noted well work nodes, parts, our
