HW$04-04$

Determine the horizontal displacement at A$.E=29x{10}^3$ksi. The moment of inertia of each member is

indicated in the figure. Assume $D$ is a pin support and $A$ is a roller. Use method of virtual work. $($Answer to

check: ${}_A=0\mathrm{.}124$ in $($to left$))$

HW$04-05$

For the portal frame, evaluate the horizontal deflection at $C$ and rotation at $D$ using virtual work method. Take

$EI=$ constant. $($Answer to check: ${}_C=27,456k.f\frac{t^3}{E}$I $($right$))$
