“…Taka forma pracy i zniszczenia dźwigara została scharakteryzowana jako swoista "pseudo-plastyczność", pozwalająca na wczesne "ostrzeganie" przed nagłym zniszczeniem dźwigara, charakterystycznym dla konstrukcji w pełni kompozytowej. Jest to jedna z charakterystycznych cech dźwigarów hybrydowych, potwierdzona także w kolejnych badaniach [6], [7]. Bardzo podobny dźwigar był przedmiotem badań i późniejszego wdrożenia w Australii [8].…”

“…The long-term bending curvatures could be reasonably predicted by a simple analytical model that considers the high strength concrete's compression creep as the deformation controlling mechanism, while as pointed out at the beginning of Section 4, the prestressed CFRP tendons and the bond thereof to the HPSC are assumed not to creep [25]. This modeling is based on a similar approach as described in [37]. In particular, the controlling creep law for the HPSC was estimated by performing two outdoor compression creep and shrinkage experiments on unreinforced HPSC hollow cylinders of a diameter of 100 mm, a wall thickness of 26 mm (the same cross-section of the poles) and a height of 360 mm for eight months near the bending creep test rigs.…”

“…13 and 14 from the beginning of the creep tests), predominantly, the concrete compression zone creeps under the long-term load, while the load bearing capacity of the concrete in the tensile zone is neglected. In [37], a model to calculate long-term bending curvatures was developed for a concrete-GFRP-CFRP hybrid beam. The authors assumed that shrinkage and creep of the hybrid beam components can be modeled by strain and stress redistribution to satisfy the equilibrium and kinematic compatibility conditions.…”

“…Custom designed beams have been proposed to address these shortcomings albeit with mixed success. The most successful are those that combine FRP with a core material, such as concrete [1,2]. These concrete filled beams appear to have solved many problems.…”
