In the previous paper (Part 2), we proposed a set of wind force coefficients for designing free-standing canopy roofs, based on a series of wind tunnel experiments. The wind force coefficients for three types of roof geometries, i.e. gable, troughed and mono-sloped, were derived from a combination of the lift and aerodynamic moment coefficients. Assuming that four corner columns supported the roof, the axial forces induced in the columns were regarded as the most important load effect. The present paper investigates the validity and application of the proposed wind force coefficients. First, the coefficients are compared with the results of the LRC method. Then, it is discussed if the coefficients can be applied to the other roof supporting systems, for example, when two center or edge columns support the roof.
