Title of the articleDetermination of the monolithic steel-reinforced concrete floors effective beam width
Abstract.Problem statement. The purpose of the study is to determine the design width of the slab of independent «T»-section beams and ribs of a monolithic composite section of steel-reinforced concrete floor or slabs. Based on the analysis of technical domestic and foreign literature, the task is set to identify the state of the issue on the design width of the slab as independently used beams of «T»-section, and beams that are part of a monolithic reinforced concrete floor. Based on the analysis of the stress-strain state of a bent composite section of various types of floors, write new analytical expressions and obtain formulas for determining the estimated width of the shelves of the «T»-section. Results. The main research results consist of an analysis of the current approach to determining the design width of a slab, identifying the stress-strain state of a bent element of a «T»-shaped composite section and deriving a formula for the estimated width of a slab of a t-steel-reinforced concrete section. Conclusions. The significance of the results for the construction industry lies in the identification of the stress-strain state of a bent steel-reinforced concrete element. The research results, analytical expressions for assessing the strength of the «T»-section of steel-reinforced concrete floors can be used in the construction of ribbed plates and beams of new buildings in steel-reinforced concrete, wood-concrete, precast-monolithic reinforced concrete versions and in the restoration of ceilings of buildings that have served their standard life.
Keywords.steel-reinforced concrete structures, «T»-section, shelf width, analytical dependencies.
