Floor Beams Reinforcement Effect on the Spandrel Beams

This paper investigates the effect of steel reinforcement of the floor beams on the analysis results of different floor to spandrel length and depth ratios(lf/ls) (hf/hs). This study investigates the behavior of seven full-scale spandrel- floor beams using nonlinear three-dimensional finite element analysis via ANSYS 14.0. The results reveal that positive reinforcement in the floor beams significantly enhances performance, particularly after cracking, by redistributing internal stresses and allowing torque to transfer back to the floor beams. This interaction leads to increased load-carrying capacity and reduced deflection without altering concrete cross-sections. Ultimately, the findings highlight the importance of reinforcement strategies that satisfy both structural and economic requirements for optimizing spandrel-floor beam assemblies.
