Abstract


The paper presents a method of producing Circular Cross-Section Columns (CCSC), which can provide sufficiently precise dimensions, with longitudinal reinforcement securely fixed in special plugs. An investigation procedure for determining the capacity of CCSC at all the stages of their loading with eccentric pre-stressing has been presented. Based on the conducted experimental work, load carrying and deformation parameters of the strain-stress state of reinforced concrete CCSC have been obtained. The investigation results make it possible to define calculation prerequisites and fracture criteria of the deformation method of calculating compressed-bent elements of CCSC at transverse bending and reinforcement deformation below the yield point.
