Syllabus
4.- 5. Deflection computation of the two way slab within Scia Engineer computing program with the help of non-linear calculation.
6.- 7. Deflection computation of the two way slab within Scia Engineer computing program with help of linear iterative computation – non-linear behaviour is taken into account by modification of the stiffness matrix within every iterative step.
8. Tasks submission. Credit.
