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.
  • 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.
