[en] This study investigates moment redistribution phenomenon for pin ended double-span steel-concrete
continuous composite beams and arise a question about moment redistribution for the continuous beams subjected to partially distributed or concentrated loading conditions. The overall objective of the study is to propose a methodology to fulfil the technical gaps adopted by Eurocode-4, which considers the redistribution for only uniformly load condition. A robust iterative algorithm is developed to obtain moment-curvature relations of the standard composite cross-sections. Flexural stiffness-curvature relations of the cross-sections are predicted through the moment-curvature relations. Flexural stiffness distribution along the composite beams is determined with curvature compatibility. Fourth order differential load-deflection equation is evaluated with finite difference solution scheme for continuous beam conditions and variable flexural stiffness along the beam length. A non-iterative incremental load-deflection algorithm is developed to calculate moment distribution in continuous beams with variable flexural stiffness. A benchmark example is solved with Eurocode- 4 provisions to validate the developed algorithms. Moment redistribution from hogging (negative) zone to sagging (positive) zone of uniformly loaded double-span continuous composite beam is illustrated considering the degree of flexural stiffness degradation in the composite medium. A question is arisen for moment redistribution in the continuous beams subjected to partially distributed or concentrated loading conditions. | |
