SYSTEMATIC REVIEW OF LONG-TERM BEHAVIOR IN COMPOSITE BEAMS.

Composite steel-concrete beams are an economical and efficient solution for building and bridge applications. However, In the analysis of structures, only the instantaneous deformation is often taken into account, but long-term loads can cause more significant deformations for the same applied load. This work concerns the effects of time-dependent concrete behavior, such as creep and shrinkage, which include service and ultimate limit states. So the general aim of this research was to evaluate the long-term flexural behavior and functioning of steel-concrete composite beams through a systematic literature review. It was possible to do a qualitative analysis of the increase of deflection and slip through time and effects in dispositions of strains in long-term loading. After that discussion, it was possible to deduce that long-term behavior can vary a lot in the characteristics of the shortterm exceeding design code provisions. However, there is still a lack of data in experimental results for more detailed analysis. [ABSTRACT FROM AUTHOR]
