- u(x)=(1-x/l)*u1+(x/l)*u2 Horizontal displacement

w(x)=(1-x/l)*w1+(x/l)*w2 Vertical displacement

hello

i hope everyone doing well,

I have problem in Stiffness Matrix For Beam element (2 nodes )

i have a beam element i want to get a stiffness matrix:

we have beam element (2 nodes)

node (1) : u1 horizontal displacement, v1 vertical displacement

node (2): u2 horizontal displacement , v2 vertical displacement

i know that the stiffness matrix is the relation between the forces in nodes and displacement

ke : Stiffness Matrix

D: displacement

F : forces

N : shape function

rotation are 0 .

stiffness matrix will be

i want to know if the sttifnes matrix is correct if not how can I get the correct one ?

thank you
