Q10. Calculate the maximum total (net) horizontal force in the N-S direction for checking the building stability (ultimate limit state) using the combination of the windward and leeward loading on the walls. For simplicity, assume the horizontal forces on the roof and side walls are negligible. Also, assume that the wind direction multiplier (M_d) is 1.0 and that the building is not sensitive to dynamic wind effects. For this example, also assume the factors K_l, and K_p to be equal to 1.0.

a) What is the design wind speed V_des,θ? [m/s] [1 d.p]
