The Design of Non-Linear Structures Using a Small Micro-Computer
Some structures combine a requirement for a high degree of safety with the drawback of difficult structural analysis. An example which may be cited is a prestressed concrete pressure vessel for a nuclear reactor, and it is now some 23 years since this problem was first tackled. Methods of linear analysis were developed, principally by Dynamic Relaxation and Finite Elements. It was also essential to establish an adequate safety factor for the vessel, and that was met by making and testing a scale model. This proved to be expensive and time consuming; it could also lead to uncertainty if the full size vessel had to differ from the model.
