Semko V. The estimation of reliability of steel beams with damages

Object - steel beams with defects; the purpose - an estimation of reliability of steel beams with defects on the basis of the analysis of their is intense-deformed condition; methods - experimental methods of research of the is intense-deformed condition, methods of building mechanics, the mathematical statistics, the probability and reliability theory; novelty - dependences which give the chance to improve a design procedure of steel beams taking into account length of cut of a shelf are received; the technique of definition of admissible horizontal curves двутавровых beams has received the further development; the is intense-deformed condition of steel beams with different types of defects is experimentally investigated, features of work of steel beams with cuts are found out; it is developed and investigated mathematical models of steel beams with different types of defects a method of final elements; it is executed calculation of reliability of steel beams taking into account defects; For the firsttime it is defined factor of working conditions depending on the sizes of defects of steel beams; branch - building
