Voskobiinyk O. Regulation methodology of technical states of steel-concrete composite structures

The object are steel-concrete composite constructions of buildings and structures in service; the aim is to solve the problems of failsafe operation of complex steel-concrete structures through the establishment of methodology of estimation, differentiation and regulation of their technical states; the methods are theoretical (structural mechanics, mechanics of deformed rigid body, mathematical modeling) and experimental (full-scale and laboratory), technical diagnosis, mathematical statistics and probability theory, technical risks theory; a typology of defects and damages, as well as the theoretical basis for estimation and regulation of technical states of steel-concrete composite structures based on the analysis of new experimental data, indexes of actual faultness and complex methods of risks management have been first developed; probabilistic criteria, models and approaches of reliability estimation and regulation of technical states of steel-concrete composite structures in service; the principles of formation of steel-concrete composite structures under reinforcement, the maximum allowable values of typical defects and damages, recommendations for estimation of technical states of structures, proposals for defining a partial safety factors; implemented during auscultation, reinforcement designing and construction of steel-concrete composite constructions of buildings and structures, introduced into the normative documents of Ukraine, applied in the educational process in universities; the field is Civil Engineering
