Year of the Tiger
I don't envy you your self imposed task, you will I'm afraid find it quite difficult to get any detailed drawings as they were long ago buried in the archives of two now non-existent companies - Sud Aviation and British Aircraft Corporation.
The best source of overall structure drawings I have seen is that on the HeritageConcorde.com site. which also gives some explanations of the structural concepts. The Haynes Concorde Owners Workshop Manual also has some interesting data. One problem is that the loading conditions on the various bits of the wing varied so much and the whole thing was so finely optimised for weight saving that there are many different structural concepts used.
You (and others here) may find a 1999 lecture given by Dudley Collard (a much respected Concorde design engineer) of interest. You can find it at
