Reconsider the two composite columns and their cross-sections previously introduced in Question 2. Assume that these columns are subjected to the same sustained shortening displacement 65 applied at time to and maintained constant afterwards (see time axis below). This displacement & is assumed to produce a total strain ) at time to. oA do | > 0 to time Provide a qualitative description of the variation over time due to creep effects (do not consider shrinkage effects in this question) of the following variables for each of the two columns considered (i.e. columns 1 and 2 introduced in Question 2): 1) deformations in the concrete 2) deformations in the steel 3) stresses in the concrete 4) stresses in the steel For each of these variables (i.e. deformations in the concrete and steel, and stresses in the concrete and steel), comment as to which cross-section (i.e. cross-section A-A of column 1 or cross-section B-B of column 2) is expected to exhibit higher deformations and stresses in the concrete and steel
