In this project assignment, a billboard will be placed on a platform built on the ground. It has a schematic view as given below. 1. The wind force acts on the billboard (a) and (b), the weight of the billboard (c) 2. The billboard will be placed on the pole indicated with number 2 and its length (d), the height of the point where the spring is attached from the platform (e), the pole profile (f) 3. The steel beams indicated with the number 3 will be placed on the steel legs indicated with the number 4 and the platform will be placed on them. Beam length (g), foot length (h), beam and foot profile (i) and (j) respectively 4. Section 5 is determined as a spring connection between the pole and the ground. Thanks to this connection, it is planned to stand against the effect of the wind. Spring constant k(k) and deformation (l)a) 30 N per m2 area
