enter image description here

$A_{st} = 200 mm^2 \hspace{1.5cm} E_{st} = 2 \times 10^5 N/mm^2\\ A_{At} = 370 mm^2 \hspace{1.5cm} E_{7 \times 10^4 N/mm^2}\\ A_{Br} = 370 mm^2 \hspace{1.5cm} E_{Br} = 8.8 \times 10^4 N/mm^2$

Elemental stiffness matrix,

$K_1 = \frac{AE}{L} \begin{bmatrix} \ 1 & -1 \\ \ -1 & 1 \\ \end{bmatrix} = …
