Vysochan N. The influence of the processes of constructing on the stress-strain state of ferro concrete components in carrying systems of multistory buildings

The object of research – processes of designing and taking into account the processes of crack formation in the elements of ferro-concrete framework structures that have been used during constructing the buildings and constructions for different purposes; goal – to creation of calculation model for the stress-strain state of ferro- concrete components in frame constructions of multistory buildings including the processes of their constructing, crack formation and duration of load based on the numeral analytical method of boundary elements; methods – analysis of literature sources, theoretical and numeral study of work of the ferro-concrete framework structures, ferro-concrete mechanical methods, comparative analysis of data received and calculation results using the program complex; results – developing the calculation model of the stress-strain state of the ferro-concrete structures in frame constructions of the multistory buildings taking into account the processes of their constructing, crack formation and duration of loading action, which is based on the numeral analytical method of boundary elements and program; – developing methodology for using the numeral analytical method of boundary elements to calculate the ferro-concrete framework structures including the influence of the processes of building construction and crack formation of concrete; - developing the program in the MATLAB computer mathematics system, which allows constructing the linearized diagrams "moment of flection - flexure" and makes possible to estimate the stress-strain state of the ferro-concrete frame structures taking into account the processes of duration and constructing of the building, creeping and crack formation of concrete; introduced – for the project practice of Stikon LLC, the building organization. Also for academic process at the Odessa State Academy of Civil Engineering and Architecture to prepare students of the second (master’s) level of the educational-scientific program “Industrial and civil engineering”.
