Draw a steel building having a length $($depth$)$ of $30m$ and the in$-$plane dimensions shown in the following figure and nerform the wind loads calculation:

Use Steel S $355,$ sections: HEA for columns and rafter $($main system$),$ IPE for the purlins and UPN for the wall girts $($side beams$).$

The supports are fixed at the bottom of the columns at level $0.$ The wind velocity is $20\frac{m}{s},$ the site is normal and near the coast, the building is on same level of the sea. The permeability of all building sides is supposed to be equal to $0$ except the front side it is equal to $30\%.$

The dead load of the cover is $7K\frac{g}{m^2}$ and the dead load on the side walls is equal to $7K\frac{g}{m^2}.$ The live load on the cover is $25K\frac{g}{m^2}.$ Apply the self weight automatically and add the Dead Load on the purlins and side beams and the live load only on the purlins.

Create automatically the combination loads at ULS and SLS

Perform structural analysis and determine maximum Bending Moment in the structural elements at ULS. Determine the maximum deflection at SLS for the purlin and the frame.

Create groups of purlins, side beams, columns and rafters.

Design optimally at ULS the purlins, side beams, columns and rafters.

Check at the SLS$,$ the maximum deflection of the structural elements.

Provide all the calculation notes of wind loads and design at ULS and SLS $.$

Save the model of the structure as $.$rtd$,$ and calculation notes in a file with your complete name. Compress the file and send a copy on the course message of CAD course.
