Below, there is a rigid frame with an internal hinge at the middle of the horizontal beam. a. Calculate the end reactions and draw the shear and moment diagram for the given rigid frame. b. Design the beam and the two columns, using steel ST37, which has a yield stress of \( 360 \mathrm{MPa} \). - Consider factor of safety as \( 1.4 \) for the allowable stress for both beam and the columns. - Select your sections according to European steel sections. - Neglect the self-weight of the structure. - Do not consider the deflection limit (for the beam) and the slenderness limit (for the columns)
