Show me the steps to solve $(45\%)$ In a renovation the designer decided to keep front facade of the building and renovate the roof

and the back part of the structure. Therefore, a frame as shown in the figure below, needs to designed. Design

the middle of the three frames. Use the following load combination $($STR$)$: $1\mathrm{.}35G_k+1\mathrm{.}5Q_k^s+1\mathrm{.}5{}_0{Q}_k^w,$ where

leading variable load is the snow. Transform the loads to linear loads on the frame. The bending rigidity in the

beam and column is the same, namely $EI.$ Use the force method to determine the maximum bending moments

in the beam AB and compare it with a system with an internal hinge at point B $.$ How do the maximum

moments change? Compare the values. $h=4m,d=5m,=15$deg,$b=10m,q_p=1k\frac{N}{{?}^2},c_s{c}_d=1,G_k=$

$1\mathrm{.}5k\frac{N}{m^2},S_k=2\mathrm{.}75k\frac{N}{m^2},C_t=1,$ where $G_k$ is the characteristic dead load, $q_p$ is the peak velocity pressure,

$S_k$ is the characteristic ground load. For snow consider undrifted scenario, $C_t$ is the thermal coefficient for snow

load. For wind in the roof consider only the positive $c_{pe}$ coefficients, while for the column the negative one

$($negative means wind suction$).$ Wind is coming at angle $=0.$ For tributary area: consider half of the distance

between the frames from each side. Topography is normal.
