Dmytrenko T. Stress and strain state of monolithic beamless reinforced-concrete floor connections with steel reinforced-concrete columns

Object - connection nodes monolithic girderless bezkapitelnoho overlap with the composite column, composed of channels, welded in a "box" and filled with concrete, a meta-study job junction monolithic concrete girderless overlap with the composite column based on experimental and theoretical data. Determine the mode of deformation and fracture behavior of samples nodal connection reinforced concrete girderless overlap with composite columns; innovation - developed and studied theoretically proposed new design solutions nodes connect concrete monolith girderless bezkapitelnoho overlap with composite columns with channels filled with concrete, obtained new theoretical and experimental data on bearing capacity and stress-strain state of the proposed nodal connections when exposed to static loading, improved calculation method for determining the strength nodular cast concrete connection girderless bezkapitelnoho floor while working on punching considering longitudinal reinforcement, the method of calculation proposed nodular cast connection girderless bezkapitelnoho concrete floors with composite columns for the proposed method of calculation nodes connect to bursting carried automation calculating the programming language Visual Basic for Applications; results - based on the analysis proposed new design solutions hub connection reinforced concrete girderless bezkapitelnoho overlap with the composite column with channels conducted experimental studies of the proposed design solutions node connection by comparing calculations bursting strength by different methods. The calculation of the length of shaped metal parts in nodes connections reinforced concrete floor slabs with composite columns, evaluated the stress-strain state and strength calculation nodes connection reinforced concrete girderless overlap with composite column, the calculations strength of the connection monolithic girderless overlap with the composite column additionally taken into account the effect of longitudinal reinforcement plates for the proposed method of calculation nodes connect to bursting carried automation calculating the programming language Visual Basic for Applications; implemented on a number of construction projects, industry - construction.
