Why is the deflection of a reinforced concrete beam in RSTAB / RFEM in condition 1 different from my manual calculation?

Answer

It is often the case that the selection of out-of-date materials may have an impact on the deformation of the beam. Please note that the material properties should always be taken from the respective standard. The material properties of the same material may differ depending on the standard and its National Annex.

There was selected the same concrete for this example, but the concrete C35/45 | DIN 1045-1 has - compared with concrete C35/45 | DIN EN 1992-1-1 - a smaller modulus of elasticity (see Figure 1). Consequently, a larger deflection is created in the mid-span of the reinforced concrete beam, which is only loaded by its self-weight (see Figure 2).
