Prepared by: Res. Asst. Burak AKBAŞ Question 1: For the reinforced earth wall shown below, calculate the followings. Necessary dimensions and soil parameters are provided within the figure. There is no ground water level. Strips are made of galvanized steel and they have a width of 75 mm. Their yielding stress is fy = 3.105 kN/m². For the horizontal forces, utilize the Rankine's theory. Assume that the reinforcements are extensible. Part a: Calculate the required thickness of the reinforcements including the corrosion if the design life of the wall is 50 years and corrosion rate is 0.03 mm/yr. For this, you should check factor of safety against tie-breaking for the most critical strip. Take FStie-breakingmin = 3. Round-up your result to the nearest integer. Part b: Calculate the required length of the reinforcements. For this, you should check factor of safety against pull-out for the most critical strip. Take FSpull-outmin = 3. Take friction between soil and strips as sol Surcharge = q = 20 kPa 111 0.75 m ist strip Sy = 0.75 m Sh = 1 m 6 m Granular backfill c' = 0 kPa ' = 28 y = 19 kN/m - 8th strip 1m
