The plan and 3D elevation of an earth retaining structure used for support excavation is shown in Figs. 3 and 4 respectively. The retaining structure is made of wood planks supported in the horizontal direction on vertical steel piles (HP sections). The HP piles shape of an H and are typically used for piles. The section properties of these sections (A, I, S, etc…) are given in Part 1 of the AISC steel manual. The spacing of the supporting HP piles is 20ft. The height of the piles is 15 from top of the pile to top of the footing. The height of the water table from the top of the footing is 9 ft as shown in the elevation in Fig. 4. The pile height and soil properties and the earth pressure distribution behind the retaining structure are shown in Fig. 5. Figs. 6 shows the equations for earth pressure. q is a live load surcharge that accounts for traffic on top of the embankment; q is typically assumed to be 250 psf (per the bridge code (AASHTO)). Use Fy = 50 ksi 1. Determine…
