Our son has to create something tall for science class (grade 7) to examine structural stresses and physics (a variation on the match-stick bridge project) out of any chosen material from home. So, naturally, he is planning on using Lego.
We have been going straight up with 4 stud by 4 stud squares using 2x4 bricks and reach the ceiling easily enough. It wobbles and leans but falls if gets any external pressure. Clearly a fatter column will do better, (already started) as will a heavy foundation, but buttressing is not allowed. We figure the next section in the study unit will be about improving the towers so we need to leave some room for improvements in versions 2a, 2b, 2c.....
I am sure there are lots of Bricksetters with experience and he would love to hear about past efforts. If you could share stories and projects it would be great.
Also, and perhaps more important is finding a reliable resource text. An engineer buddy couldn't find anything in his resources specific to Lego :-).
Thanks in advance.
