Title of the articleCalculation of the carrying capacity of the chimney during dismantling
Abstract.Problem statement. The purpose of the study is the strength assessment of reinforced concrete chimney during dismantling by roll method. Results. The results of modeling the loss of bearing capacity of a monolithic reinforced concrete chimney during the dismantling by the method of directional rolls are presented. Two variants of the calculation for determining the size of the opening in the trunk of the pipe: a) the pipe is considered as an eccentric-compressed elastic column; b) the pipe was modeled as a thin conical shell of variable cross-section in the LIRA package. The stress-strain state of the pipe was investigated depending on the depth of the hole in the trunk of its own weight, as well as taking into account the tension of 17 tons from the excavator. The calculations were performed both in geometric and physical linear formulation and taking into account the nonlinearity. The results of the calculations and recommendations were taken into account in the preparation of the project of works for the dismantling of the chimney. Conclusions. The significance of the results for the construction industry is to develop recommendations for the safe dismantling of chimneys and other similar high-rise structures.
Keywords.chimney, dismantling, felling, the size of the opening, the barrel of the pipe.
