Please show work Thank you Problem 66 Consider the simple f

Problem 6.6. Consider the simple frame shown below. Assuming that all members are inextensible in the member axial direction (i.e. infinitely stiff) and the all members have a bending rigidity of EIde termine the condensed stiffness matrix Ktt (i.e. statically condense out axial dof is considered the rotational degrees-of-freedom). Note simplifty your answer as much as possible. onal 0,7 2 L 1.3L

Solution

Stiffness is depend on the carry over factor(COF) and cof is depend on the type of support .

Now ,

For fixed end =4EI ÷L^3

For hinged end =3EI÷L^3

For free end =0

In this questions, add to all cof and get the value of 24•85EI÷L^3
