Correction: Steffen et al. Structural Performance of Textile-Reinforced Concrete Sandwich Panels Utilizing GFRP Shear Connectors. Constr. Mater. 2025, 5, 92

Text Correction

There was an error in the original publication [1]. In Section 3.2 (Moment–Normalized Deflection), the examples cited for EI-based stiffness comparisons were not appropriate.

A correction has been made to Section 3.2 (Moment–Normalized Deflection), in the paragraph beginning with “Unlike some studies …”, which should read as follows:

Unlike some studies that compare stiffness using elastic moduli and moments of inertia (EI), for example, Choi et al. [20] and Lyu et al. [21], the present evaluation relies on the measured bending moment capacities. This approach avoids the uncertainty of estimating effective EI values in nonhomogeneous sandwich cross-sections and provides a direct and experimentally grounded assessment of composite action.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
