Effective width of Concrete Flange
This chapter illustrates the method of calculation of the effective width of the concrete flange due to shear lag. The method is recommended in clause 5.4.1.2, EN 1994‐1‐1. It is considered that a continuous composite beam consists of two spans and a cantilever. We need to calculate the value of the effective width of the concrete flange beff for the mid‐span regions AB and CD, for the support regions BC and DE and for the support at A. Elastic global analysis may be based on the stiffness calculated using the results for AB and CD. However, the differences between these values are so small that the structural element ABCDE can be analysed as a beam of uniform section with the effective width of the concrete flange beff = 1,650 m.
