Turzhansky P. The tensile-deformed state of concrete tube elements which can withstand tensile stresses

The object - concrete tube elements working in tension. The aim - elaboration of methods for estimation of the stress-deformed state and calculation of carrying ability of the centric and eccentric stretched concrete tube elements on the basis of experimental-theoretic investigations. The method - an experimental-theoretical one, containing choice, studies and analysis of literature sources. On its basis the aim and the task of the work, the fulfillment of experimental and theoretical investigations of concrete tube elements working in tension are formulated. The practical results - the estimation methods for the stress-deformed state of concrete tube elements working in tension were worked out. The methods for determining of carrying ability of concrete tube elements working in tension with various eccentricities were grounded, which will be user at elaboration of a new normative document in Ukraine (SBN) "Steel-iron-concrete structures". On basis of received theoretical dependences the algorithm of calculation on ECM for estimation of the stress-deformed state in concrete tube elements working in tension was created, which is being offered for utilizations by planning and design organizations. Design work and building of structures with utilization of the stretched concrete tube were realized. The field of application - civil engineering.
