Darienko V. Deflected mode of flexible anchors of steel-concrete composite beams of uncuts

Object - flexible anchors in steel-concrete composite beams; the purpose - development and perfection of method of calculation of flexible anchors in the steel-concrete composite beams of uncuts on the basis of experimentally-theoretical researches of the deflected mode of constructions; methods - experimental, methods of mathematical statistics, method of eventual elements; novelty - conformities to the law of change of the deflected mode and bearing strength of flexible anchors are first discovered in the steel-concrete composite beams of uncuts on length of construction at the action of the static loading, developed and adapted methods of calculation and planning of flexible anchors in the steel-concrete composite beams of uncuts taking into account pliability of anchors, forces of friction between steel and reinforced concrete parts, plastic work of materials, changes of sign of bending moment on middle supports in statically indefinable beams; results - the method of estimation of bearing strength of flexible anchors is specified in the steel-concrete composite beams of uncuts, which takes into account their geometrical, physical mechanical and structural features simultaneously, a program algorithm is developed for the selection of necessary amount of anchors in the explored constructions by computer on the basis of the offered method of calculation; degree of introduction - on 4 objects on Ukraine; industry - building.
