This session is not intended to teach concrete design, but more of an awareness of why things are the way they are In this paper, a design procedure based on the structural model using the generalized single degree of freedom (SDOF) system is proposed for concrete rectangular liquid containing structures (LCS). For a piled foundation, uniform support along the full length of the wall can be provided by adopting piles at closer spacing with a first storey capping beam. For example, you can create a lazy tongs mechanism, and it works great on the solid modeler, but then when you build it, something different hap-pens.
