Shear-Lag Phenomenon in Cast-in-Site Reinforced Concrete Hollow Floor System
Shear-lag phenomenon exits in many long-web structure especially when the stiffness of web is much larger than that of the flange’s. In this paper, Energy-Variation Method is applied to interpret shear-lag phenomenon in cast-in-site reinforced concrete hollow floor system. Finite Element Method (FEM) and is then used to validate the analysis results. The solution for the variation equation for effective flange width is proposed by solving the differential equations using proper boundary conditions.
