Description:

Statically determinate 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 determinate, therefore modification of the stiffness influences deflection, but does not influence internal forces (in contrast to statically indeterminate structure).
