Investigation of creep behavior of various types of reinforced concrete haunched beams

İngilizce (OpenAlex)

In this study, the influence of creep was comprehensively investigated for both prismatic and non-prismatic reinforced concrete beams using finite element analysis, while taking a prior experimental study into consideration. The research was conducted in two stages. In the first stage, the reliability and accuracy of the finite element modeling approach were assessed, and it was concluded that this method is suitable and effective for examining the creep behavior of reinforced concrete beams. In the second stage of the research, a comprehensive parametric study was conducted to determine the effect of each parameter (such as load values, load types, compressive strength, tensile reinforcement ratio, water-cement ratio, aggregate-cement ratio, relative humidity, and shear span-to-depth ratio) on the creep behavior of both prismatic and non-prismatic beams. The results indicate that creep deformation is more pronounced in non-prismatic beams, where the inclination angle notably influences the structural response. Consequently, the load-to-capacity ratios were adjusted to account for the increased creep effects.
