of e creep over a long period of time is not well captured by the actual model. The impact of moisture content changes over time should also be accounted for in an upcoming revised version of the proposed model.

Fig. 3. Comparisons between the deflections measured xperimentally and the ones determined using the analytical proposed model for notched beams DF1 (a), DF9 (b), WF6 (c) and WF9 (d). Table 1 presents the main characteristics of these notched beams.
