Description:
Statically indeterminate frame loaded by vertical distributed load and horizontal force.What can be modified:
- span of the frame (length element 2),
- height of the columns (elements 1 and 3),
- magnitude of distributed load,
- magnitude of forces,
- bending stiffness (EI) of all elements,
- normal stiffness (EA) of all elements.
Notice:
- the structure is statically indeterminate, therefore:
- modification of the stiffness influences both deflection and internal forces (in contrast to statically determinate structure).
- parts of the structure with higher stiffness "attract" internal forces.
