This paper explains the stiffness adaptation analysis procedure in DIANA.
The stiffness adaptation method is explained and compared with standard nonlinear iterative approach for reinforced concrete applications. The new method is easy to use and efficient for calculating crack-patterns, crack-widths, onset of yielding of reinforcements and load-displacement-curves at pre-failure load-levels. The stiffness adaptation analysis is illustrated by various examples.
