The loading pattern’s influence on the stress increment in prestressing steel and bending moment resistance in multi-span members post-tensioned with unbonded tendons
Languages of publication
During the design process of members post-tensioned with unbonded tendons, deformations of the whole structure between anchorages, having impact on ultimate value of prestressing force, shall be considered. The conducted researches enabled the separation of several parameters influencing the stress increase in unbonded tendons – i.a. the loading pattern in multi-span members. This paper presents selected codes are shown and compared.
